Nice game! I was able to complete all of the puzzles. I would say the puzzles do involve a good bit of thinking and planning. However, the puzzles did require some trial and error. I don’t really think that was a big deal though because I enjoyed every puzzle. I had a lot of “aha!” moments throughout.
I like the art style, it reminded me of those games they’d have installed on our elementary school computers (educational games) and also Pizza Tower.
I would find a way to make the mechanic more obvious in the first level, but I was able to figure it out after a bit of experimenting.
Good work!
