WASD should be the default movement controls instead of the arrow keys (just like every other first person game). You do give the option to remap the controls though. Also, puzzle games need a hint mechanism for when the player gets stuck on a puzzle. Last, why release a demo when you don't have a product to sell? Demos are supposed to get a gamer hooked on your game and then you sell them the full game. A demo without a full game is pointless.

I downloaded the game and worked my way through the puzzles rather quickly. It's basically impossible to fail. As I'm walking down into the basement, hearing the voices say "come here, come here come here"... The game suddenly ends. "Thanks for playing the demo." Umm. Ok. How do you get the rest of it? No clue.

I would like to play the whole game. But how? Where do I get the complete game. This is annoying. You play through the game and get down to the basment then the game is just over without telling you how to play the complete game.

I'm not sure why the ratings are super critical. It ran fine on my 2012 MBA, and it was a pretty good way to spend 20ish minutes. Granted, it wasn't the best puzzle game, and sure it was short... But it was a free demo. FREE. I'm happy with it, and it was a fun little game to take up some time.
