Cool concept but you might want to look up the way that you're supposed to write some of the characters like 人 and 心. Also, assuming this is the Japanese interpretation (since you said kanji, not hanzi) 心 does not mean heart, it means mind. It's up to you, but it might be easier to just change the name to hanzi chaos or something.
It's mostly based on Japanese since that's what I was studying during my free time, but 心 can mean heart and/or mind, as Kanji can have multiple meanings. I suppose the energy could be represented as both physical or mental health, but either way that feature has not been implemented yet. I may use a different engine in the future if I still can't figure the health system out yet, and the game could look completely different than this one demo does, I'll probably move the double death block gap to a much later part of the game for example. Thanks for commenting!
