Short and sweet but really fun while it lasted. Like swinging on an old swing set that's on its last legs and laughing when it breaks and you fall on your ass five feet away because you were mid-swing. Ah, the good ol' days.
I will admit, the game could use a little polishing, because movable blocks can push or carry you into the terrain. I first encountered this with the block at the bottom of the screen that carries you to the right after the small puzzle where you have to move one block out of the way of another block that you need to move onto the circle-X button. I was curious if it would push me off when it went under the platform ahead, and it actually carried me into it. This wasn't a problem because I came out the other end just fine and could jump to the next platform to continue as normal. After that, I replayed the game to take the route you were supposed to, and when I got to that part and jumped up to the ledge I ignored before, I wasn't paying attention and kept moving the block to the button while I was still standing in it. The block pushed me into the platform, and even after moving the block back, I couldn't get out. Couldn't jump up or walk to either side. I was completely stuck. The former situation is more of a polishing issue than anything, something akin to speed-running glitches, but the latter actually interferes with gameplay. This game is a few years old, though, so I don't expect any changes to be made.
That said, I would definitely play a longer, multi-level version of this game. I love the visual style and the gameplay. Incorporating holding the mouse buttons to move the blocks was a pretty cool feature and something I don't see in many games. The music fits nicely and was pleasant to listen to as well.
