Everything about this game is incredible. The one and only thing I struggled with was the screen management. It's one of those things where "it only takes 5 seconds to switch between screens" but those 5 seconds feel exponential during the midgame. A bit more of a smooth transition between shop/park/team management would have made this an easy 5/5. Maybe the shop and the team management as a pop up on the park screen would be enough.
That said, this is a really fun game, with surprisingly good balance and progression. The guys are cute, and seeing them grow up makes me so proud. Great job!
