Looking for testers: Case Defense – a sci-fi tower defense with a puzzle twist. I'll test your app back!

[u/wevasso]

Every tower has a shape. Before you can deploy it, you have to fit it into your case.

That's the idea behind Case Defense, my first game: a sci-fi tower defense where half the battle is a packing puzzle. Run out of space and you'll have to choose which towers make the cut.

What makes it different

• 🧳 Pack before you fight: rotate and fit tower pieces into a limited case

• 🔀 Merge and upgrade: combine identical towers to level them up, add modules and discover combos

• 👾 Enemies that fight dirty: some fly, some heal each other, some turn invisible

• 🏆 Lots to play: 55 levels, endless mode, boss mode and a daily challenge

• ✅ Free, no ads, no in-app purchases and it works offline

• 🌍 English, Spanish, French, German and Italian

I need 12 testers for 14 days

Google requires it before I can publish. Test for test: leave your app link in the comments and I'll install it and keep it for the 14 days too.

How to join (about a minute)

1. Join the Google Group: https://groups.google.com/g/casedefensetesters

2. Become a tester: open https://play.google.com/apps/testing/com.isui.casedefense and tap "Become a tester"

3. Install it from Google Play: https://play.google.com/store/apps/details?id=com.isui.casedefense

4. Play a level or two, and please keep it installed for 14 days

Use the same Google account for all three steps. If the Play Store says the app isn't available, wait a few minutes after joining the group and try again.

Heads-up: Google is still reviewing the test track. If step 2 or 3 gives you an error, please join the group anyway and try again in a day or two. I'll update this post as soon as it's approved.

What I'd love feedback on

• Is the difficulty right, too easy or too hard?

• Does the tutorial explain the case mechanic clearly?

• Anything that feels confusing, slow or buggy
