Nice job, I've always wanted to be an intellect devourer protecting myself from a virus infestation! I think you did a great job balancing the level waves, they had a reasonable increase in difficulty to make each level a little harder than the last without spiraling out of control. 

After five or six levels the game started to feel a little repetitive, so I might have liked to have seen new enemy types or maybe the opportunity for temporary powerups. 

The addition of the dwindling lighting as you ran out of lives was a nice touch, good job!

Great atmosphere. Nice mechanics. I might have like autofiring instead of click-to-shoot. Otherwise, great game!

Really cool game! Got so frustrated, but in such a goooodgood way! I couldn't get past stage 4 for the longest time and when I finally got to stage 5.. the sense of victory I felt was incredible! xD  

Nice little wave-shooter. Liked the Brain-on-legs-sprite!

Cool atmosphere on this one. I liked it. Congrats on the jam!
