Very cool game! I like the simplistic side of it combined with the very creativ idea. I would only suggest not to give the player tiles which he will die to quickly (or do it maybe so that you have an infinite amount of rerolls, but each one takes a lot of time, so it feels less unfair for the player).
But nevertheless a very solid game!

Currently in the game, every time a new tile gets generated, it will always be able to be placed on the previous tile (unless it would be placed directly on another existing tile), however adding another check to make sure the tile won’t lead into a wall is a good idea. It would probably make the game more fair.
