Wow. I can tell you put a lot of effort into this. I remember playing the prelude/tester to see whether or not you'd consider making more. and its been polished so much since then. Excellent job. 10/5 Fav'd
The game itself seems to be extremely computer taxing and just overall laggy. Maybe some quality options or finessing to fix this issue? It very annoying that my mid-end laptop gets a system wide lagspike for just running the game.
black screen usually means there is a problem loading the game. You may just need to wait a few minutes.
