First off good job implementing the player. It feels very good. The dash especially. The art is also nice. The puzzles felt like a good difficulty, not obvious yet not frustrating. You also did a good job slowly introducing your mechanics, which meant you did not need a tutorial. (BTW are sticky blocks making other blocks sticky an intended feature because it seems hidden). The one thing I would say is that the level with the spike tunnel before you get the dash for the first time is very difficult, and would be a quitting point for me if I had to go back past it to reset blocks(it possible I forced a solution that should not have been tried ¯\_(ツ)_/¯ ) Just moving the dash get to that level would make it easier. I was impressed with the number of levels it just keeps on going! Great job, congrats on your submission!
