You have to hold space to restart the game. Did you finish the level? if yes, what grade did you got?
Yes, abviously the art is dry but i didnt spent much time on it any way.
Yeah, it is kinda annoying that the bullets hit the walls and the enemies can go throught but i kinda wanted to have it as a main challenge. The main thing I was going for was the game mechanic that the health=ammo=stamina (although the stamina doesnt really has an importan use).
