Very good
This is a great idea - platform game in which you can make your own levels. You really should add some more feautures, character movements, powerups etc. There were some glitches, the one that was most annoying is the "ability" to stick to walls. objects and *sigh* spikes. You can even jump off them, which can lead to ease of clearing levels... which I consider cheating.
You made a great game and I hope it will become one of the popular net flashes and make it to the frontpage :P.
P.S Here's a small level:
