First of all, congrats on your first game jam! Just completing a project and uploading it is a great achievement in itself :)
Anyways, this game was very cute. I like the idea of keeping the talking flowers alive, and the art style was very appropriate for this type of game. The music was also quite nice. You've also implemented the special object very nicely, as you are a literal bucket lol.
I will say that it seems like the optimal strategy is to only keep a small group of flowers alive near the well. I was able to infinitely keep a small group of flowers alive since they spawned so close together and near the well.
Good job!
Edit: I just realized the title of the game is a pun for "dedication", but you're dedicated to preventing the flower's decay, hence de(decay)tion
