I really like the atmosphere, the game was a bit boring in that you walk a lot, and I think I got stuck because I couldn't find another crystal to kill those worms. Maybe showing where you are on the map or where the crystals are could help. And having some sort of music at the menu could help, I thought it didn't have any audio and that sound effect at the start kinda scared me lol. But other than that it's pretty good!
If you could check out my game too I'd appreciate it (or at least tell me if it loads, some people seem to have issues loading it...)
