Hi guys, thanks for the comments. I will admit I'm a bit green when it comes to distribution. I am working on a compiled version as I type this, for Windows and OS X.
@stqn Thanks for the heads up on the bug, I will get on it. Also thanks for pointing out about the arrow keys/WASD, too much coffee and not enough sleep meant I didn't think about non-QWERTY keyboards.
Everything is intentionally slow by design, the goal is just to survive and there is a hunger mechanic in there - the longer you leave it between eating (i.e. if you sit at the cave and sleep all the time) you will become weak and end up using more energy to move. This is an area that took quite a bit of tweaking to get right, maybe a bit too ambitious?
