neat start for a jump'n'run game. cool story and fitting graphics.
i like the little decorations (i.e. the signposts)
the conveyor belts are a bit surprising (not noticable beforehand) and the movement could improve from some comfort-options (like "late jump" - a very small counter after the player reaches the end of a platform where one is still able to do a jump)
Music and SoundFX would improve the game too
