Thanks a lot for your comment! First of all, yes, the idea to use only stone for the buttons was mine; using torches as well would have made it too simple.
Also, once you pick up a torch, its timer keeps running—and eventually runs out—even if you drop it on the ground; that was a deliberate design choice :D
Finally, since the main goal is to stay alive and every round is so short (1 to 4 mins), I dont want to provide an immediate explanation for every monster; if you do get killed by one, the game tells you exactly which monster got you and offers a tip on how to avoid it or survive.
As for the controls, I built this game so fast and don't really see a long-term future for it, so I likely won't be releasing any updates. I'm currently working on a new, large-scale online HTML5 project, so I don't have much spare time. That said, if the game becomes even a little popular, I might expand on it significantly. Thanks so much for playing! <3
