Good visuals (i.e. this game has unique, distinctive art style), but they can only help shifting the initial sell, and I couldn't find anything for me to stay with the game 'till completion, because you'll end up revolving around a few dozens of screens multiple times to find a missing piece of a puzzle (and you're not sure which puzzle exactly you're trying to solve at any selected moment). If you're more into puzzle solving than item hunting and vaguely aimless walking, I'd suggest avoiding this purchase (to be fair, they do feature the open worldness of the game right at the top of the description, so you've been warned)
Non-redefinable controls, especially on PC, is an absolute show-stopper. I do have a controller that I occasionally use in selected list of titles, but I'm accustomed to playing many platformers with WASD + Numpad keys for jump/attack and other actions. Unfortunately, there's no way (not even a workaround) to change controls in this game.
