I would have had no idea this was your first 3D game in 48Hours, had I not read your description! I am mighty impressed!
The gameplay is fluid and fun, and the puzzles are tricky, yet not too much so!
The 3D visuals are flawless and look Great! The 2d visuals, however, are a bit low res, as I can clearly see pixels on some elements, but that's a nitpick!
Overall, a really stellar game, and an amazing first shot at 3D in 48hrs. Well done!
