I'm still working on saving and loading games because I didn't have a spare moment last week to work on this.  However, to show that this hasn't been dormant, here's a new screenshot, where you calibrate your grayscale if you haven't played before.  You can even fine-tune the grayscale using the right and left keys

Note: Omnimaga doesn't seem to want to play the whole file, so you should click on "Calibration.gif" to view the whole thing

I'm not yet ready to release my next legitimate screenshot, but here's a few snapshots.  I was really worried about how the ice textures would turn out--but I've got to tell you, even though I haven't finished the sky, I felt really chilly doing a test of this level 

Looking good!

Wow, this is looking real nice!
