Made it to about wave 11 before they got me.
Overall a good concept. I personally think it would have gone well with a MIDI soundtrack or something.
And I also agree with the pink patch + pink pathogen = hard to see.
I'm not well versed in music at all, making a track of my own would be worse than the silence presented in front of the player. So since I couldn't find a song of my liking, I decided to focus on the gameplay instead. I appreciate your time.
