It's hard to believe that this is the result of just one month of developing. Excellent combination of graphics and music and gorgeous atmosphere, a very professional demo indeed. The retro taste is definitively there, but the game flows smoothly and you can see that there's a very conscious and up-to-date developer behind the curtains. I experienced some very minor issues as far as controls are concerned, but reading the other comments it seems that the problem has already been fixed. That said, this is a very promising game and I can't wait to play the full version! Definitively one of the best entries here, if not the best one.
