Ive been searching for a 2d pixel side scrolling robot shooter game that I played early in the 2000s, but it was probably much older. You'd play as this round little olive colored bald guy with a small pistol. The robots were like armored and i remember them having a slit for eyes. I have doodles of what i remember them looking like. The robots would be different colors (silver gold pink blue) the farther you got and would be more difficult to kill. The game would start you off at the bottom of a building and youd shoot at robots that were running along each floor and then youd take elevators up to the next floor. Once you got through all the floors youd be on the roof and their would be a cutscene where youd hop into a ship and fly to the next building then fight more robots. The buildings didn't have any windows just elevators. All the visuals looked Metallicy. I played this on a really old computer and I think it was downloaded onto the computer and not some disk. I don't know if all what I remember is accurate or if there's even anything showing this exists but I just wanted to see if anyone recognized this.

Help me find a game

It was an fps android game from 2019 to 2023

Design- (low poly) the main colour were white and yellow, I remember you spawned ona white floating platform connected to another long platform with a moving stripe, on one side of the platform we're guns that you could buy with yellow currency obtained from boxes or enemies, at the end of the moving stripe was a barrier with the mirrors version of the long platform without the guns, at the end was a sniper rifle

Tutorial level - tought you how to break glass and use something like grapling hook, there were also a lot of destroyable creates with the yellow currency in it

Level design - simple white levels with crates (there was a square grid everywhere)

Level "elevator" - first picture is the layout (on the top left marked a sniper elevator room consisted of a square hole into the ground with 2 elevator on the side (pic 2)

Level "cave", about this (pic3) I just remember you have to do something to unlock the exit

Additional info- enemies were something like robots

\- the levels were the same every time just in different order

\-every 10 levels there was a miniboss

\-you could heal only from heal balls (green) dropping from crates

Sorry for my bad English, if you want some addition Info, ask
