Excellent game. Great graphics, great gameplay, great idea.
I had an immense amount of fun beating it.
One peeve though is that holding down the shift activates Sticky Keys on the computer. So, maybe changing the keys will save some people some aggravation.
Another thing that annoyed me slightly was that, once I "Alt-tabbed" to another application and tried to switch back, the graphics were all messed up (almost everything was black).
However, my overall opinion is that this is one of the best games on here. I am surprised that you have both artistic and programming talent. It seems to be a rare and enviable combination.
On somewhat of a tangent, I tried downloading the 3d version from Mdickie's web site, and it didn't work right. For some reason, the gameplay area was just a black screen.
