Thanks for the bug notes on the forums! I've been working to resolve some of the issues folks were seeing on some machines. I just pushed some updates that should take care of:
* Black Screen bug (UI is visible but the game isn't)
* Skipping bug (Nemo appears to glitch as he's walking)
There are also some minor level improvements, performance improvements, and minor changes to things like enemy placement and improving overall playability of the demo level.
Thanks for all the feedback so far! We really appreciate it!
