very difficult...
the mouse movement was super slow for me, so just turning around was a pita. never understood what I was supposed to be doing and just died immediately so the whole 'crafting' thing was completely lost on me.
took me like 3 or 4 times to figure out that there were traps on the ground - kept thinking I was stuck on collision geo in the world or something...there's no sound fx for things like this so it is very hard to understand what's going on.
