Link's broken and I don't see any similarly-named projects on your page, so Ionno, but just brainstorming from the sounds of it, maybe there are different kinds of squares and you can mix them up to give you different abilities, Kirby 64-style. 3 water blocks gives you a strong water beam, 2 water blocks and an ice block has you shoot larger water bullets that slow enemies, that kinda thing.
Or, the squares themselves are parts (think parts to a ship or mech) and their position can change your combat and movement capabilities (like having a "push" block on the bottom lets you jump, while having it on the side allows you to push enemies away, or air-dash). That kinda thing could be fun to play.
