Really nice and polished game, I enjoyed it a lot! I think something you could consider is having all the instructions available to you for each level, so you could use the move right/move left/jump/... instruction for whichever command you want. I think that creates a lot more room for experimentation, and allows for multiple solutions which will improve the experience as there is room for replayability and each solution feels more "personal" to the player.
Btw, there is a bug in the instruction select screen where if you drag over multiple instructions it picks them up all at once, and the instructions can sometimes return to points just slightly off the "slots" they are supposed to be in.
