It should be functionally complete, now.
I think I may have made something of a beast.
What's in store:
6.5 MB download
5 music tracks
Hours of gameplay. (It took me 2 hours to grind through it from start to finish, and I knew how to solve all the puzzles!)
The ice walking isn't quite working how I want it yet, but it does not interfere with gameplay as it is, so I'm hoping to get some feedback.
If you want to get hold of the playtest version, it's here:
(Slightly newer version with some fixes in)
Let me know via pm or what have you if you intend to playtest it, and good luck!
