Cool take on the theme, reminds me a bit of the rocket jumping from old games like Quake and UT mixed with a bit of Portal. I could see it expanded with different objects having to be set up before you create a chain reaction of the character just getting blown up, sliced, spiked etc.
Would be nice if the time between retries was a bit shorter as now you first have to wait for the character to fall down, then respawn, fall on the ground and get up. This takes a bit too much time when you're just trying to go again
Overall a nice game, good job!
