CubeMania by Sand3r is a PSP homebrew application featuring 3 small puzzle games, called FillUp, Matrix and Slide. They’re all quite similar to each other as they have the same design and idea: a game board that’s made out of cubes, basically just squares.

Quote:

– FillUp – Level 26 fixed: it was unable to solve;
– Previously selected theme now applies automatically at start up;
– Possible to test your newly created levels;
– Matrix is now even more bug free. A rare bug might came up about ‘solving’ the level, while that wasn’t the case * Thank you Mad Mark for all your support
– In PushIt it’s no longer possible to push a crate to the next row when you push it against the outer edge (like word wrapping);
– Added some more advanced PushIt levels.
