I enjoyed both Sokobond and Cosmic Express, and this feels like they had a baby.

The visuals in this game are really simple, but clean. The music is charming and fits the mood of the game well. While the game is quite fun, it isn't very difficult. Each area consists of 5-6 levels, and typically only the last level or two of an area will offer much challenge, taking maybe five minutes or a little more. IIRC, the game felt much simpler than Sokobond, and was certainly easier than Cosmic Express. The final level of Cosmic Express was insane. Only one level in this game gave me any trouble. And it wasn't even the last. Beat the last level in a few minutes. For whatever reason, Pi-6 really just had me stumped.

If I account for leaving the game up and running, this game probably took me around eight hours. A little pricey if you look at it that way. If you look at it as a fun puzzle experience, the asking price is worth it. But if it's on sale and you like puzzle games, particularly Draknek and Friends published games, it's really a no brainer.
