Was a little fun to play around with. The levels were elementary, but still required me to think a bit because of the new mechanics. A good difficulty for novices to the genre, but perhaps others would want a greater challenge! I was satisfied. The music was good.
I was impressed that it came with a level editor, and I made a small level to confirm some mechanics I was not familiar with (for example, can you change direction if you are falling?).
Nice submission, looking forward to what else you might work on!
