When you extract the game, the files scatter everywhere, it would be better for the files to be inside of a folder.
The main menu effect where you shoot the options is very creative, the info blends with the options, making the text hard to see.
In the mini game: The enemies can hit each other, making them miss bullets, it's a nice touch that you restore life by killing, but running out of ammo is not fun, maybe make it so it also randomly spawns on the map, also the map is like an empty void, i didn't know i was actually moving until i reach a white wall, this is my score:
I hope you can understand what the numbers are because i sure can't. also some enemies are in front of the options.
The game lacks music or sound, i beat the boss but i couldn't get through the final door, not even sure if there was something there.
