Nice thinking game, but I couldn't figure out how the boss fight works, (how to damage him)

I don't see why people say this game is great, for me it's impossible to play. the controls are awful I can't move from one side to another without the dude getting stuck, when I press on A sometimes nothing happens and other time it does rotate, I jump, the cube moves but the dude doesn't. I don't get it. and also the cube is too small so you have to get really close to your computer

Эта игра очень похожа на "Vanessa Saint Pierre Delacroix And Her Nightmare!
Мне нравится игра.

Awesome game! I rarely give five stars, but this game deserves them.

Very innovative puzzle game, though I have seen a game where your character traverses the surface of a cube once or twice before. I do wish there could have been a bit more to the story than silent acting and a few notes in the author's description here on NG. That and the music not being separate from the sound are my only complaints- I would love to be able to mute just the music so I can listen to my own, but still have all the other sound effects from the game.

The learning curve gets appropriately steeper as the game progresses. I like this. It was stupid tough getting the last few levels finished, but I still managed to figure it out. I now have all 18 diamonds and the super-secret surprise that rewarded my efforts. Now I'm looking for the nine keys, but I've no clue where to go. The game gives no hints about their whereabouts. I can only presume they are hidden within the previous levels since... well, I don't want to spoil too much for the players.

However, dear author, if you are still checking up on this, any hints about the keys would be appreciated.
