Really nice game! Had a ton of fun playing it, here are my notes:
-items are nice, keep that they have no description before buying
-make health cheaper (can't buy anything else when being hit)
-game softlocked after mothership failed to kill last drone in fight against junkjard golems
-player-character too big
-player artstile doesn't fit the lowpoly rest of the game
-katana animation/weapon holding -player movement animation is always walking forwards, even when he is walking backwards
-remove the dirty vaseline on screen (bloom-texture)
-make it more obvious when hp lost -> red screen pulse?
-red barrels must equal explosion -> make current barrels blue or smth and add new red barrels
-higher default movement speed?
-jumping is pretty useless right now (you can jump over tank shots)
-make it a way to dodge vertically?
-levels with multiple elevations?
-dashing into enemies never damages the player
-make that random?
-close doge = hp- reward?
-tanks do flick on player sometimes (when noticing you)
-gas thingy glitches in red colour at his "wheels"
-gas thingy is not fun to play against imo
-gas hitbox too big, too much hp
-make it a burst fire tank?
-general quicker enemies with less hp and more of them?
-camera a bit further back + let the cursor move the camera further
-enemies need to remember last know location and search the player there, not home in on hime with wallhack
-they sometimes notice you randomly
-add grenades? (to not use a weapon slot!, random enemy drop, only from special enemy?)
-make automatic weapons have a longer default range
-what is the counter in the top used for?? -add a reward for a high combo (damage boost, hp, more scrap)?
-junkjard golem: give laser movement delay so you have a chance to hit him while he is firing it -flamethrower: needs longer range
-what is up with all the BIOS-esque blue in the game? maybe do a bit more with that theme
