This game was created for the 2013 Cleveland Summer Game Jam in less than 48 hours.
It's pretty (slightly intentionally, though) unbalanced, very short, and not very pretty in some aspects.
However, unless there's a game breaking bug, I won't be working on this again...
I just watched a trailer for the upcoming 2021 JRPG Fantasian. They demonstrated an interesting mechanic where random encounters can be sent to a stockpile instead of fighting them right away, which can be emptied in a single battle string at the player's choice of timing.
