Here’s what I have so far, still nameless as of yet:

Mechanics are implemented as I think they work best; playing around with them in this test level over the last four hours or so has allowed me to work out any defects and improve the general feel of gameplay.

The remaining, parts I’d like to get done, in order of priority:

1. Create fun, interesting levels (hopefully with some interestingly challenging puzzle elements)
2. Update graphics slightly (that doorway is hideous, I don’t know what I was thinking)
3. Create Music (sound is already taken care of)
4. Create Title Screen
5. Create Ending Screen
6. Create Splash Screen

We’ll see how it goes.
