Played the whole game and have to say that it was fun. It looks like the kind of game that would be fun to play on a mobile as nice and cute puzzle game. I believe the teleportation idea can expand and create even more interesting level design. Keep up the good work.
Despite being very simple it can be a blast playing with a buddy. As almost everyone else mentions a bit more complexity (time constrain is a legitimate reason) would make it a real winner.
Interesting enough idea. It feels like a horror survival game despite its simple premise. But it does end up with being a simple find exit game within time limit.
