Lovely art style and interpretation of both the theme and the prerequisite, balancing between health and spending is a great mechanic. The sound design is excellent as well. As another said, the left menu didn't feel as useful as the right one, I only ended up opening it once just to try a few things but didn't use it again. Still though, amazing art, design, and entry, thanks for letting us play! :D
p.s. the first time my fish exploded to level up I jumped up in my seat bwhaha
