Dude this was so freaking cool. Absolutely loved the 3D effect upgrade! When I first started I didn't understand why I could go through some tiles and not others, and eventually when I got one I couldn't get through I experimented with the arrows and figured out what I had to do. Maybe you could start the game in 3D and it could do a couple rotations just so the player can see? Anyway, loved this. Great job!
