The sound effects are a bit tricky for this type of games were enemies/player tend to shot a lot, so you need to choose a sound effect very carefully to not make the gameplay annoying. In this case I was about to make my own sounds effects but the time become a problem, so I ended up using some old sounds that i created a while back(Player damage and Enemy death explosion) and one that I downloaded at the last minute. But i'm glad you like it anyway, thanks for playing!
