Really simple but fun idea, and the black-and-white art style looks so cool. Chasing every bubble could get a little annoying, but I liked that you could ignore them. I may have hit a small bug near zero, though.

I got there in 49 seconds! :D

Very simple, but also pretty fun and a really neat idea. I think there's a bug when you enter the splotch right around the time you hit 0? Not entirely sure, but one time I felt like it did the counting down to the next number but ended up skipping one and killing me.
