Thank you for your feedback, I highly appreciate it!
Object pooling was in my plans but that was my first time doing this kind of object intense game and I just didn't know how to. BUT! I am going to rewrite some stuff here and hopefully optimize game for the better.
About controls I tought in a way as "3 main actions to control in the game" but to make it a little bit easier for people who may have different preferences I made so that you can use each of the actions with multiple buttons ( I know about keybinding but it was more of a cheap and fast feature to implement )
Also I apologize about editing game files, I thought if it was possible to edit files it was okay to make minor changes to the game. I will add original game's file as an option to download.
Thanks for playing :)
