Warning for some light spoilers!
Super cute art, characters, and concept! I love little projects where you just try some novel battle system idea, in this case balancing the HP bar instead of trying to get it to 0. I would love to see a version of this where the battle system is expanded upon. Right now I think the dominant strategy is to save a lot and kiss your way into a good beginning state for the battle coming up then just beat on the enemy in whatever direction they are closer. If there were multiple endings based on how you defeated enemies I think that would add a ton of replayability since you would have to play drastically different in every route. Definitely could use more skills and status effects to take advantage of as well. I had a ton of fun figuring things out! I wanted the side characters to smooch each other more than I wanted to smooch them I will not lie I think watching them come to understand each other better was so sweet.
Would love to see it with an actual ending! Great job!
