This is a really fun and unique game, I would definitely buy/play an expanded version. I saw someone mention Valkyria Chronicles as the inspiration which makes perfect sense, I was thinking of it as an epic player-controlled Xcom meets a Heist game.
The donkey's names were really funny. And the character models and the animations were really endearing. The donkey mode was cool and fun although I didn't use it much as the player character, I mostly tried to run down and snipe the bandits in cowboy mode.
Something interesting happened to me, unfortunately while watching the Bandit turn one of them in donkey mode had 2 health and ran past some of my cowboys on his way to steal another bag, and my cowboys shot him dead after missing a few times which instantly crashed my game :( I was on track to have 2 bags left and I think all of my cowboys.
Very fun game, I hope the development continues after the jam and/or that it becomes a standalone game for purchase, it's so unique and the gameplay loop is solid.
