Hehe, nice idea. Do have some remarks:
- Timing is off now and then, I just blazed through the levels while you were still talking.
- Double jump thing worked, but I got three blue chips in the end, I think, and I got double jump, triple jump and antigrav jump
- In the last level I could stand antigrave on the moving wall and it pulled me inward through the red block towards the door.
- Also, the spikes don't work after the level you 'fixed' them. In that level I could also just run towards the door before you fixed the spikes.
- Maybe it's a nice touch to say "Oh no, no cheating" and transport the user back
