Thanks for your feedback. Your game has lots of potential too. I very nearly had nothing to show for this Jam as I broke it pretty bad just before I had to submit. It's hard being a Solo dev when everything is your own fault! I use Jams to force me to get better at the stuff I don't really like doing. Mostly finishing things! I can see my progress from Jam to Jam.
I am working on a Post Jam version and it is already a much better experience. I will post it once the Parade is unlocked.
In terms of the Healing selecting it directly is pretty high risk. It is more successful if you can counter or combo into it. I am thinking of new move types that should create more interesting chains. It's been fun to refine it now that the time pressure is off.
