You might have this game lying around, whether in your Steam Library or Humble Account, and either way I'd say give it a try if you haven't, it's quite a pleasant puzzle game.
The core gameplay of Eets Munchies is very simple - Eets, the white dog-looking guy there, wants the cake, and is very single-minded in this desire. He will walk until he either reaches a wall or obstacle, when he will turn around, or when he reaches a ledge, where he will (usually) jump. This is usually not enough to reach the cake on its own, so you have to help him, using a variety of passive or activated items.
These range from wooden platforms/barricades, or items that will change Eets' mood to angry or frightened. The levels are small and only have a few items each, so it's usually fairly easy to tell what the game wants you to do, but it still feels clever when you pull it off, thanks to the nice animation and relaxing soundtrack. There are some physics and timing related puzzles, but they're not too common and usually not so bad. The game's not very long, so maybe get it on a discount if you don't have it, but if you really like puzzles I'd say it's worth full price.
