Nice game! I spent about a hour to gather full party.
I think it would be better to increase health gain by level, and remove Fitness.
Whoa that's awesome!! I hadn't even done that myself, glad you enjoyed it and that k you for taking the time to play! I really enjoyed working on this and want to revisit it. The version of idle combat I'm working on for a traditional RPG Maker game is a fair bit different, I kinda want to come back to this and work on it some more 👀
Also, I think you're totally right about health. It would make more sense to do it by level, I found myself not really investing in it a whole lot unless absolutely necessary (which most of the time it wasn't).
