This was an interesting game to play through, it's relatively simple but it has a lot of ways it can expand.  Though the on page description of the game really doesn't cover the actual gameplay.  So I feel like updating that would help a lot, get more people interested with that and a tag line.  A couple finer points of feed back tho:

• The game does get a bit repetitive since the main patterns have so few variations.  So I feel like either expanding the palette or adding more randomization could help?
• As well I generally never really needed the extra from losing health, so I just kept it all.  Adding some areas where that speed is needed could help?  Maybe taking advantage of the jump to jump on a platform to get off the floor cause of spikes and spikes falling?
• The jump feels underused and a little weird to have in. Since it's not actually used in the main setups throughout the game.  I feel like expanding on it could really vary up the gameplay a decent amount, though it's up to you how that could be implemented.

Overall it's a nice game to waste time on, though there seems to be an issue with the highscore counter since I hit 15000 and it still said my highschool was 200...  With a bit of polish and variation like I suggested it could really be fun to just mess around with.  Though it's up to you how far to take it.

Good concept!  If you polish it a bit more, it could be a great mobile game!
