Played this way more than i should, seems i'm a sucker for auto battlers.
Feels like a basic prototype that has most of the needed mechanics for a proper auto battler, but somehow i never found a combination that was op.
Ofc theres lot's of work to do, like giving unlimited time for the starting setup. As a new player it's weird that the game starts immediately upon buying a character, still looking what each does. Also the tooltips confused me more than they should, they should always pop up when hovering over specific attributes. I'm not too sure how they were triggered, but it felt like clicks triggered some and hovering some others. That needs to be unified and intuitive.
I think i encountered a bug, repositioning a character when dragging them immediately when the round starts. Not 100% sure about this, since it didn't happen again.
Like others said, the exp -> party member limit was confusing at first. The game would be easier to understand if some error feedback was shown when trying to put characters on the field when at the limit.
