I really like this! I only have two wishes. I wish I could hit a key to start the onslaught immediately / wait a second to mentally prepare myself when I die (my level of patience depending entirely on whether I've hit the checkpoint or not). I also wish that jumping into the bottom of a falling block before it hits the ground wouldn't kill me instantly.

I decided to play this again and beat it! Is the ending a nod to WarioWare?
