This was actually really fun, the sound effects are hillarious :D I also like how fast paced it is, though it does feel bad when you are near a spawner and an enemy spawns in you, so i kept hugging the wall on the bottom in the end, i like how you tried to encourage going somewhere with the Powerups tho.
Weirdly enough just the second enemy gave the game a lot more depth, i should have made one aswell ^^'
I played for quite some time trying to beat my highscore, ended up on 1100.
Great submission!
