Good concept, but interface could use some work.
I like what's trying to be done, granted it is extremely difficult at times. (Took about 15 min to get level 10, only to once again.. get stuck at level 12 *I gave it 10 min.. and just could not get the hang of switchjumping)
What I would like to see in the future is an improved menu screen, show us what levels we have completed and lock the ones we haven't. As much as I'd like to attempt to master this game, I do not like having to redo the same content again to get there (especially level 10, rockets almost always glitched right after the 3rd jump) This would also allow others to practice some of the difficult moves in the game and master them for the later levels.
The concept is overall good, this game has a fairly large learning curve.. so isn't for everyone, but that's fine. Just add more functionality into the game menu (quality, levels, maybe even a difficulty option) and it should be better.
