The maze seems to sometimes have invisible walls, and have the walls that are there able to be walked though. No title menu, no in-game tutorial, no HUD showing time remaining, no 'continue' or restart button (no buttons at all actually), and if you wander off the maze at the top you have to refresh the page to continue playing. That's five things wrong with this game, and that's why I took five stars away from the review. It's a good rough draft to continue with though.
