Loved how much personality shone through in this game, a pokemon-like auto-battler is a cool idea too. Very ambition putting it all together from scratch in a week!
I think if you make your scope way smaller next time you'll be quite successful. The game idea you choose should feel like it can be achieved in half the time of the game jam, because you'll inevitably be delayed by bugs and want to have plenty of time to polish before the end.
You should be quite proud for delivering this game, though. Despite the bugs, I enjoyed my time with it :D
