Very fun, I felt on top of the world until a boot brought me right back down to earth. It was interesting that you seemed to slow down when you lost friends, I would have thought it would be the other way around, but it let to some interesting gameplay where you are really far in and getting hit once makes it more likely you will be finished off.
I did run into a few technical bugs, such as the gamplay and title music playing over each other, but overall there's a decent amount of polish in here
