Could be really awesome if it had good music and good backgrounds, and if you really wanna go all out, make it like a challenge where you unlock doors by solving puzzles. Those usually get you saved.
The Only thing I would have you change was the fact that you have one of the Matchstick Puzzles (I can NEVER get those)
The graphics themselves were not all that good but then when have graphics ever made the game? As long as it doesn't look too bad and as long as I can play the game, that's all that really matters.
