this is SICK, one of my favourites, with a tiny bit more of polish, more levels (or an endless mode) and more varied visuals id pay for this on steam or the play store and play it all the time! i love the ricochet bullet mechanic and being able to have your bullet hit multiple enemies in a line, it really makes you be mindful of your long reload time, and the visual (screenshake, the combos, etc) and audio feedback (sfx and the music when you win) makes it even more satisfying. theres a lot of bugs honestly and things that some people would consider "broken" but some of em make me like the game even more tbh. i love how in some levels theres an explosive barrel that if you hit it you automatically win, i love how you can get absolutely swarmed by enemies cant even move but you somehow manage to get by and you dont even understand how you won, and i love how you can play the next level even if you lost.
seriously good job!
