I for one found this to be quite a satisfying game, and agree that it is a great demonstration of Unity.
It's a 3D platformer, but the use of gravity shifting and wall-running allows it to capitalize on all three dimensions in a way that shifts the player from the camera adjustment and (ironically) linear exploration that are the focus of similar games.
These mechanics make the game feel less "twitchy" which favors relaxed mental engagement over more common (and more stressful) difficulty-increasers like jump timing and mobile threat avoidance. There is a time-limit on the floor-sticking ability, but it is long enough that no area in game requires its complete expenditure and short enough to encourage the player to plan ahead rather than solve puzzles with the brute force of simply running all over the available surfaces. There is one point where jumps must be coordinated with the rotation of boxes, but even this element is employed in a new way within the gravity puzzle format.
You can get 455 diamonds without paying, but you won't get above 400 until you beat the game. For this reason, and because it owns, I recommend getting the 300 diamond TITAN SLAYER as soon as you can afford it. It is significantly better than the most expensive guns and makes the last level a breeze. Thumbs up if this helps you!
It would be nice if the mute button muted all the sound in the game and did not mute the sound on my computer. Right now it stops Pandora from playing when selected and every time a mission ends... and I still hear sounds from the game.
I'm surprised nobody has mentioned what I feel could be the biggest improvement to the game: the ability to tweak or fine-tune designs by dragging ends of pieces... also I don't see why I shouldn't be able to draw a piece without starting at an anchor point.
I thought the new angles were cool until I realized it means there are only 3 pieces in the game. The first two were plenty easy as far as logic puzzles go. This one is just pointless as a puzzle, but has the advantage of being winnable during the player's meditation or even sleep.
