Really nice game with a cool message but a bit lacking gameplay wise. The art style was really nice and the message is solid.
I saw in the other comment that you had less time for the jam but if you ever decide to improve this, here's some things I think could improve your game:
- The player starting either in front of the tree directly or some sort of path leading to the tree so the player doesn't start off the game wandering aimlessly.
- The game starting with the frog dialogue panel wondering where they are to set off the scene
- Perhaps future tasks could include finding items in the surrounding water or having to talk to the other characters for information only they know (because of where or what time they lived in before their extinction)
Other feedback such as more atmospheric items (grass, flowers, etc.) seem pretty obvious so these are just things I wanted to add. Overall your game definitely has a lot of potential and if you do continue it, I look forward to seeing how it develops.
