It’s a bit like Tetris, Puyo Pop, etc. Blocks fall down the screen, you move and rotate them and try to get three of the same colour to line up, at which point they disappear. If you remove all the hollow blocks, the level ends and you start again.

Compression

Not a lot of room left. I may well die soon.

The twist is that every now and again the walls of the level move inwards, making it like playing Tetris and Bejewlled in the trash compactor on the Death Star. Only without Luke whining his way through the whole game.

But I needed a purple shape! It's so unfair!

It’s nice conceptually and it’s lovely and polished, but the controls let it down for me. Too often I’m trying to rotate the falling shape and find myself moving it across the screen, or vice versa. It doesn’t happen all that often, but it’s often enough to annoy me.
