Cute, beat the game in 1:36. I like your asset choice, they fit well together, except the player may be a little pale. More detail in the gameworld would have been nice. Stuff like in the cave, where the background has a noticable other color kill the atmosphere, so try to avoid those areas in your game. Props for your first game :)
Nice you implemented some feedback for example feeding sound. But dont stop there, go carzy with the feedback, play particles, animate scale and stuff like that.
