Pretty tough little runner. Could barely beat 18 the first few rounds.
I like the area-concept - each area having some specifix behaviour attached to it.
Right now there is not enough room/time to abuse those mechanics - but the concept is solid. Maybe slow down a little or give the player more room to maneuver.
The music fits the game well.
For everyone going after the highscore: The hitbox only covers the legs - the black area up top is a trap.
