I'm working on a post-jam update. Not sure how long it'll be before I release it, but at the very least it'll update the art, rebalance the maths and expand the story (had to cut down on the number of bosses and focus on tightening the gameplay to get it out on time). Some of the mechanics were originally meant to be more complex, so I might prototype that as well and see how it feels (might be a case of less is more).
Feedback is always welcome regardless. Knowing what people liked or didn't like about the jam version is sure to make the update a much better game :)
