A solid educational game that takes advantage of the jam's theme very well! It even comes with narration providing facts! (Even though likely you'll be focusing on the minigames more)
The pixel art looks fairly solid, the audio is quite soothing and the minigames provide variety within the gameplay. However, I wish the minigames were more polished.
What I mean by more polish is adding more visual details when certain actions take place such as having particles emit from the player when they get hit in the precipitation stage or collect droplets in the condensation stage. It also means having mechanics feel less janky and more consistent such as having the jumping in drainage city/forest being tied to just one button or having the platforms consistently bounce the player in evaporation. Finally, try to have a shared common pixel size for the pixel art to avoid pixel size inconsistencies as well as to make the game feel more polished.
Still, you did a good job with the game 👍
