Interesting concept; a little like GORILLA.BAS of old, or Worms or similar. The trial-and-error gameplay can be quite interesting, although I still don't feel like I've fully grasped the difference between a dash and a move to the right. Fun to work out, though.
However, the game flagrantly violates the jam restrictions. An 84x48 game scaled up to 840x480 has to scale up the text too in the same ratio, and this doesn't; fitting instructions and the UI into the game window while sticking with the restrictions would have been a much more complex design challenge, I think!
