Great game. I really like the idea of power ups getting stronger and evolving over time. Artwork feels like Brave Little Toaster. Your boss looks to be a roomba, which is hilarious. Audio unfortunately didn't work on my end. Could be a me problem, but I tried two browsers and tested audio elsewhere. I wish I could have heard your music and sound effects, but I still really liked the game. Thanks!
Edit: Looking at your submission time, you're probably aware of the audio issues (assuming it's not just me). It's rough to run into trouble that close to the deadline, but you still did great in my opinion.
