I respect the challenge of making a game where you only use a single button to interact with the world!
The music and art felt very cohesive to me. They put me in mind of a show made for young children, and had a sweet, wholesome quality.
Unfortunately, I wasn't able to finish the game. :/ Something about either the parallax or the unicorn's movement seemed to trigger pre-migraine symptoms (I am migraine-prone) and I had to set it down. That being said- even during my short playthrough I could appreciate how much work was put into making this.
I think a great post-jam feature would be an indicator of which ability is being used/which ability will be used at next button press. Based on another comment it sounds like that might already be in the works? I hope you continue with it! <3
