Thanks for this excellent plugin!
Works just fine along with the VisuStella stuff, just plug it in, tweak a few easy to understand mechanics and play.
The double edged sword I find that is inherently within enemy levelling up mechanics is that it disincentivizes grinding. Luckily, I have a few tricks up my sleeve to get around that for my game.
The enemy levels and also your plugin are absolutely essential to my game since the player will be able to choose from a number of different characters, each starting in their own different scenario, but will eventually converge.
This allows me to have everything set at level 1 and go from there, instead of having to navigate having to balance end of game dungeon enemies with one character containing starter slimes because it is close to another character's initial scenario.
I gave you a rating and a follow. Be interesting to see what you come up with next, but thanks for making this little gem.
