Thanks for the great feedback, I'm glad you really enjoyed the game!!
I do plan on fleshing things out more after the jam period ends so I may mess around with how certain mechanics work, but as it is now yes that is essentially how the game's meant to be. My hope was for players to incentivize trying out each beast at least once throughout their playthrough, but I see how that can make it really difficult since it's not something that's the norm with there being only 3 useable slots. Common critiques from what I've gotten seem to be things subject to change which I can continue to test out leading to a later release, so I hope you're looking forward to more! ^^
