Hi Pokezelda, thanks for your comments! We are aware of a couple issues with swapping too quickly, causing glass to disappear, but we're glad you were able to get it fixed. We have proposed fixes on here and on our forums as well, and have been responding to any emails about the issue, but thanks for letting us know all the same. As I said, this is something we will be patching with the first update.
Thanks Sasunka! I'm actually currently working on porting the game to Unity at the moment. If you could tell me anything about shading vertices programmatically, that would be great, but for the time being I'm just bumbling through on my own.
I've never done the snapshots before so maybe I am doing something wrong. I'll play around with it a bit.
EDIT: I was on the wrong snapshot. I changed it to the correct one, and it's still crashing almost as soon as I load the map. :/ Oh well, I will just wait for 1.9 to play.
If you were on the wrong snapshot, it may have corrupted your save file. It's best to re-unzip (or re-download) the map and open it straight into the correct Snapshot. Failing this, just wait for 1.9 when we update it.
Stepherator0316: We have already started developing and building a sequel. No promises for when it will be released, but know that it is in the works!
