Hi. I just tried the demo but I didn´t do so well, I felt totally lost, I don´t do well with labyrinths in games (or in real life for that matter), and I find the double flashlight rather awkward, it lights up everything except what is right in front of me.
The devil looked pretty good from what could be seen when he kept beating me up, though I didn´t appear to be able to actually die, the HUD went so far as "danger" but then it went back to hurt or something like that, but maybe it´s that I didn´t really know what all the HUD elements meant.
BTW, I think those indicators might fit better in the bottom right (or left), which is where I normally look for those things.
Anyway, keep up the good work.
