Cheap and cheerful Trioncube is cute and fun with little pretension to being any more than that. It's not much of a game, the base gameplay mechanic is shallow and simple, but it somehow manages to be engaging and compulsive despite that. You'll breeze through Story Mode probably without failing once, and it's only in the later stages of "Endless" Mode that you'll encounter any real resistance. Trioncube is relaxing and satisfying to play; a great "casual" game.
If the thought of building things out of blocks and then having them turn into coins excites you, Trioncube is for you. If you like unlocking useless-but-fun SFX themes and skins, Trioncube is for you. If you're looking for a deep and strategic puzzler, look elsewhere.
