I would have liked to have more mobility while jumping but the platforming was fine enough. At first I didn't notice the platforms and walked to the right until I fell outside of the world. Good work!!

For a platformer, not bad.  The art was pretty good. The controls felt pretty good but the jump felt more like low gravity and you couldn't move after jumping but I assume that's intentional?  The confusing thing for me was the background kept confusing me into thinking it was part of the platform.  Parallax would have worked great there.  That aside, I was enjoying it. Not sure where I was supposed to go so I ended up running off the map. The far right border didn't stop me. :(  Given the constraints though, I thought it was interesting, though buggy.  

Controls like one of these older DOS cinematic platformers which gives the game a nice touch. Great game!

great use of 2 colors. ^,..,^

in platformers you generally shouldnt lock movement when in mid air, makes moving around less fun and slow. it was very unclear that you need to press "e" to press the button.  :P
