OH, this needs more levels!
Great work for a game jam, do you plan to keep working on it because I was thoroughly enjoying the gameplay until it stopped :D
With more levels and other effects, you could make a full game.
How about, it starts out as a simple platformer, second level introduces this single touch mechanic, the game then continues like that for a few levels until it introduces a "blocks move only when you stand on them" mechanic which then continues like that for a few more levels then introduce another new mechanic lets say blocks rotate until you stand on them (requires timing)
These types of mechanics could be mixed up and jumbled together to go on for loads of levels. Mix in some level design and you would have LOADS of possibilities.
What I'm saying is, great possibilities with this one, keep it going!
