Sorry to beat a dead horse, but I couldn't progress because of the jump. I was able to get through until the area with the green light and I just couldn't jump high enough to make the platform.

I gave it another spin. It was much easier to enjoy on the second go around. The jump is a bit floaty as is, but it works fine. Also, as was mentioned by someone else, the mouse look is a little crazy. It kinda feels like you have mouse acceleration on, which never quite feels right. Good stuff overall.
