Rollancat (2008)

This is a puzzle game about a rolling cat that travels through time.
It's much more boring than it sounds. This game is seriously tedious.
I think some of the puzzles are clever though, and it's pretty cute.

This game has 20 levels.
There's no "proper" save feature, but you can press F5 to make a save-state and press F6 to load it.
The other controls are all explained in game.
