It's very simple, but I like the idea! I like how you're taking the rocket jump mechanic from TF2 and turning it into it's own platformer type game! It is quite short and I would have loved for there to be more content and mechanics, but I understand that it's hard to do all that within the time limit. I really like the concept, and I think it would be very cool to expand on it after the jam is over! Good job!
