Really cool take on the jam theme! I really liked the concepts and the overall design of this game, the hero swapping mechanic is just really well done and leaves you with a lot you could explore post-jam if you really wanted to
I'd love to see this built out into a form of roguelite where you build your team and send them in to various dungeons or battles to improve over time. Perhaps each hero could also have their own health and when they go down you are limited to your other heroes. Tons of room for creativity with this one :)
Great job!
