Needed badges...but hey. A fun 20 levels.
It was a pleasant play and never too slow. I did find that I enjoyed the puzzles a lot more when they didn't have cubes in them, since the cubes add a layer of punishment for user error by forcing the player to slowly move them back into a suitable position if they get run into a wall. That said, the jelly like design of the cubes was cute, and the ability to roll the cubes by running on top of them was a great way of negating some of the issues that they bring to the design.
Overall, you set my expectations well and were able to meet them.
my favorite level is 19
could use more sounds 4.5 / 5
