It's king of glitchy... lots of blocks just stop in the middle of a straight line for no reasons, or simply turn back.
The idea is here, but lack of a lot of finitions of be a great idle.
(sorry for my english)
Edit: Got all the achievements in less two hours without doing anything, and only using the first two blocks and a teleporter (and also thanks to the glitches). That's where my point is, this game lack of something that makes it interesting or challenging
