This was super cute! I really loved the whimsy of it all, felt very fever dream/Alice in Wonderland-esque. The color palette is great, and the shading style reminds me of many older 3D games. The sense of scale is very good - you feel as small as a frog would, and the trees look very impressive in the background. I would love to see more games in this style. The only thing I would change is maybe the default mouse sensitivity - it could make me motion sick after playing for a while. I'm not sure if Unity makes it easy to change the sensitivity or not, but it's worth considering to help more players be able to play your game.
