I made the Underswap battle thing.
Jam is obviously the kid you fight in the example (although technically they only appear in duo battle with another human)
Mechanic explanation that I thought of while making the image (I just need to ramble about something here):
Stats: there is no LV and instead you increase the stats each on their own. The 10/10/10 is the default (on the image is 20/10/10)
You can get XP by acting and EXP by fighting, both can be used for increasing the stats but XP gives less stats than EXP. So you know what that means if you want to max everything out.
Enemy cap for both violent and pacifist so you can't spare one single enemy infinitely to get more XP.
On the image there is a death counter which stays for the whole game after the first death. Different death number gives different Frisk reaction.
Chara's portrait shows their current emotion. You can get temporary party members and they have their portraits too (not at the moment)
Talk and Action are basically "say something" and "do something" buttons because actions can be unrelated to the enemies.
Maybe there is something else I wanted to say but I forgot so that's it for now.
