I really enjoy all of your games for their simple, clear, well-executed concepts. This is no exception. Who knew hitboxes, hurtboxes, and random spinning could be so mesmerising?
Major thought to take this out of prototype into production would be to work on game balance -- at the moment, picking highest HP each time leads you to defeating Kings Army. Each attribute should have some weight toward a total challenge score, and decisions between two options should be difficult to make in terms of coming to understand the tradeoffs involved.
Minor thought: make the HP sliders same colour as the team. Pink sliders when facing a pink enemy threw me for a moment.
Please keep making these kinds of games You are an inspiration to those of us who are also looking to rapidly prototype fun new game mechanics. Every one of your games so far is a "wish I'd thought of that" moment, and also fun to play.
