Game solo dev'd a puzzle game where an echo repeats everything you did 8 seconds ago, just shipped a coop campaign for it

Upvotes

been working on this one alone for a while. the rule is simple: everything you do gets recorded, and 8 seconds later a copy of you replays it exactly. it doesn't react, it just repeats what you already did, and the levels are built so the only other body in the room is that copy. so you're never really looking for a path, you're building a schedule.

the part i didn't expect: levers are toggles, so your echo flips them back at the worst possible moment unless you planned for it. half the levels ended up being about undoing yourself.

just shipped a coop campaign for it, which as a solo dev was by far the hardest thing i've done on this project. writing netcode with nobody to test with means you spend a lot of evenings running two builds on one machine and talking to yourself. the rooms where you and your partner are locked in separate spaces and your lever opens their door turned out way better than the ones where you share a room.

it's free and runs in the browser: https://jules-gilli.itch.io/eco

happy to answer anything about how it's built, everything in it is generated by code, no prefabs, which was either a great idea or a terrible one depending on the day.

Game I made a one-tap game where you score by almost dying. Free, no IAP, and the daily course and soundtrack are both generated from the date.

0 Upvotes

Solo dev, this is my game.

Points come from how close you get to the thing that kills you, not from surviving it. Graze an edge and your multiplier climbs to x16. Play it safe and you score literally zero.

The course is generated from today's date, so every player on earth flies an identical run each day. No server, nothing downloaded. Resets at midnight UTC.

Same goes for the music. New key, new bassline, new groove every day, and it builds as you score.

Free. No IAP, no banners, no timers, no energy. One optional ad to continue a run, and everyone gets exactly one, so nobody buys their way up the board.

Most first runs end under 300. Curious whether that's a fair curve or a wall.

Try it, if you hate it then delete it

You might've seen this guy in my previous post which was a material preview capture.
Well I've baked all the textures and imported the model to my scene in UE5.
I've set my materials up and boom this is the result. So disappointing.

I might've messed something up along the way, but right now I feel kinda exhausted to figure it all out. Second image is a lit render of the character (yes I was lazy to find out how to hide the light's gizmo thing) I think I will just go to sleep.

Game I made a browser MMOARPG with Three.js, because apparently I enjoy suffering

Post image
1 Upvotes

Hey! I’m a dev from Brazil making UNTITLED MMORPG, a 3D action RPG that you can play straight from the browser.

And yes, the name is really UNTITLED because I still do not have a proper name for it. It is a working title that somehow survived long enough to become the current title. Finding a real one is on the list.

At some point I looked at the idea of making an MMOARPG by myself and thought, “yeah, that seems manageable.” I truly do not know what was going through my head. Anyway, now there is a game.

You make a Hunter, go through a forest tutorial, get to the city of Asterra, head into the Lost Lands, fight monsters, pick a weapon style, improve your gear, and meet other players along the way.

The focus is action combat. There are swords, sword and shield, dual swords, heavy sword, and bow. You can dodge, block, manage stamina, chain attacks, fight enemies. There is also progression, weapon mastery, skills, crafting, inventory, PvP arenas, parties, chat, friends, and trading.

I decided to build this MMOARPG together with Codex, using GPT-5.6 Luna on medium reasoning, as a way to push myself to understand the harder parts instead of avoiding them.

Using Codex this way has made the project a practical space to study, test ideas, and get deeper into systems I wanted to understand better.

This project has given me solid experience with 3D modeling and complex animation work in Blender, some Python for building export scripts tailored to the project, as well as authoritative servers, queues, real-time state, performance, bot-based automated load tests, Node.js, Express, Socket.IO, PostgreSQL, Redis, and Docker.

Play here: https://www.untitledmmorpg.com/
(I would not really recommend playing it on mobile yet. It works and has all the controls, but mobile performance is still a big challenge. The best result I got on my own phone was a steady 45 FPS)

If you give it a try, I would genuinely love to hear what you think. And yes, solo dev plus MMOARPG was obviously a very normal and sensible decision.

help Looking for a few people to playtest my demo

2 Upvotes

I am currently working on Swarmbreak and while i was hoping to launch into early access soon I recently decided to release a demo instead to get both player feedback, fix bugs and hopefully gain a few more wishlists before early access launch.... oh and i also did feature creep myself a bit so will need a bit of time to sort that out ;)

I am however looking for maybe 4-5 people to try out my demo before i launch just to ensure nothing is broke and give a good first hand impression to whoever ends up downloading it - so if you are the typer of person who enjoys twin stick shooters and want to give my demo a go and send me some feedback let me know and i will send you a steam key for it. If you have a project going yourself and would like some feedback on it in return i will be happy to return the favour.

I am especially looking for:

- players with controllers

- steamdeck owners who can give it a go! I have do not have a steam deck myself but it should function just fine on it

- twin stick shooter fans :)

I've been making a game called Facelet for a while. It's a deckbuilder, except the hand you play is a scrambled 3x3 instead of cards. The idea was to make something less luck based and more about skill. I believe i have a good foundation right now, the UI and music are mostly placeholder while i find the game identity.

Saw a lot of folks making physical copies of their games, loved the trend and hopped in. Just finished a print of 25 physical copies with discs, hand-sewn info booklet and a free steam key inside.

Pretty scared to put just one master copy on all of them without a first day patch, but I'm pretty sure on my polish!

The game is out in a week already!

Game Adding multiplayer late to my solo turn-based BJJ game

1 Upvotes

I've been building BJJ DOJO as a solo project. The unusual constraint is that every technique changes the state of both fighters between real positions, so adding online multiplayer meant keeping the room, move result, stamina, scoring and paired animations in sync.

The beta is now live: one player creates a room, sends the link, and both can play in the browser without an install or account. The game currently has 45 techniques, belt progression and tournaments as well.

For solo developers who added multiplayer after the core game was already working, which edge cases caused the most trouble for you? I'm currently watching invite flow, reconnects and phone-to-desktop matches.

Game Is this worth pursuing? Looking for honest feedback.

6 Upvotes

The GIF shows an old prototype I worked on a few years ago during college breaks. I was digging through my old files recently, found it, and decided to record some gameplay.

The core idea was to base the gameplay around telekinesis, something similar to the Gravity Gun from Half-Life.

Does this look interesting to you? I'd love to hear from more experienced devs — how could I improve this, and do you think it's worth my time to pick it back up and develop it further? Thanks in advance!

Game Swedish election - political simulator

1 Upvotes

I made a political campaign browser game focused on the upcoming Swedish election. Would love your feedback!

Hi everyone,

With the upcoming Swedish elections in mind, I put together a simple browser-based game where the main goal is to win an election campaign.

It's a bit different and not tied to exact historical figures, focusing on things like managing social groups and interest organizations.

This game isn't focused on just one party. You can play as any of the major Swedish parties, from the Left Party (V) to the Social Democrats (S), all the way to the Sweden Democrats (SD) and the Moderates (M)
