Neat concept although the bomb jump seems a bit buggy (it seems to launch you more when you are further away form the bomb which is somewhat counter-intuitive) if the bug is caused by what I think it is, this could be fixed by normalising the explosion direction vector which would make the explosion launch the player the same amount every time, you could then use the (pre-normalised) length of the direction vector to scale the explosion power.
Aside from that, fun concept with some interesting applications of using bombs to trigger buttons which gives the mechanic much more depth, very cool 👍.
