Fun game. I stuck with it until about 70 coins before I felt lost.
A sprawling level with many interesting challenges, and interesting to navigate. Several abilities to unlock and traverse. A good implementation of the genre. I appreciate the quality of the writing, also.
The presentation could use some work. The backgrounds are serviceable but bland--a bit of decoration would be very welcome. The main character has no animation, and the graphical style doesn't fit cleanly with the environment.
Lastly, with a level of this size, a map would be really helpful.
