While many games in this game jam have shrinking and growing mechanics, I appreciate how this game uses it to affect the enemies and the environment. Growing big to scare smaller enemies and shrinking to evade larger ones is very creative and implemented well! I do agree with a previous commenter that the enemy fish can be a bit unforgiving though. Also, I was able to see some enemy fish in the darkness at times, making it easier to evade them (although I'm not sure if that was intended).
While the art style is simplistic, I actually really like that the fish are represented as outlines. Spending a bit longer to create detailed backgrounds would help the game develop a unique style in the future.
Very cute game overall!
