It's a cool concept, and I was able to get a score of 90. I think the sound system is bugged though. I kept getting error sounds and the music was cutting in and out.
Thank you for playing and liking it :3. About the sound, the error sound appears when you crash into an enemy and the music does when you get infected or use medicine; I cut only two notes from a song for the effect, that's why it sounds like that :v
