Really good game. Decent graphics, creepy looking Shrek (LOL). Some suggestions:
1) More instructions on where to go would help
2) If the game has flashing lights, PLEASE give a warning somewhere in the game. This may not be good for people with epileptic conditions, so better to be safe than sorry (many people wont think of this, but I did as I'm epileptic - don't worry, I was fine, but the lights may affect others :)
Otherwise, really looking forward to the full game!
