Great game!

I liked the sokoban block-pushing and rocket chain puzzles.

That's a great puzzle challenge!
The learning curve is very good, and I loved the way you introduced new strategies to think of.
It is longer than I imagined too. Congrats! =)

That was really good, very nice difficulty curve, never got frustrating, but there was a few times I had to stop and think for a while.

This is really fun, I love the color palette.
