Strangely, I don't see a demo on Steam... Also, I guess the design decision to show censorship mosaic until character level 10 was misguided. I thought it's just a censored Japanese game and dropped it in disappointment. Thankfully I read the reviews here later on. It's a pity because the graphics are great and the puzzles are pretty interesting. Though I did have some trouble seeing all the blocks because of visual overlaps and the frequent need to rotate the camera. Maybe it would be more comfortable with free camera rotations around the puzzle, in both X and Y camera's axes, and without snapping to 45 degree steps.
