I wish I could give this a more complete review, but I also ran into issues opening the doors both at the end of the tutorial level and in the level select screen. I will say, though, that the graphics are really nice and easy on the eyes and the soundtrack is catchy. I especially like the main menu song, that was a great choice. I might also turn up the gravity a little bit on the jumps. All-in-all, it's a fun little game and I hope I get to experience more of it in the future!
