Hello! I played the game and it was good. I had some issues with android movement, but in overall game is fine. It will be a pleasure for me to give few suggestions to improve it:
1) This game contain unnecessary locations with or without some loot. Why not make optional bosses with modifications behind them? Like in school you might find a knife that can be attached to basic stick to make a spear and improve damage (on last stages stick is useless and I use guns only). For guns you may give a laser pointer modification which will be helpful for Android.
2) Bosses have a boring moveset (at least at versions I've played) So I suggest to add more random attacks in combo with different ways of avoiding them. For example, you can add a long horizontal attack to first boss which can be avoided by crouching.
3) Movement for Android is shity and I don't know how to fix it, so I suggest to make at least 2 different modes of game: with attacks and traps that require good feeling of movement and android one that require a bit less skills (I always had problems with crouching)
I hope this will improve gameplay! Good luck! I really hope this game won't be abandoned since it have a great potential!
