This is such a cute, clever game. Easy mode was definitely a little too boring, but hard mode is a lot of fun! I love the graphics and the sounds, there's such a lot of little details like the soda colors being randomized and the music speeding up alongside the game. Interpreting the theme of confinement into a soda-drinking (and swimming!) frog is incredibly creative and cute.
I think the only issue I have is that it's too hard to see the soda bubbles against the light background, but other than that, it's overall a very solid entry!
