This is great. The mechanics create some great puzzles and overall they play really well. The artstyle is also very pretty and looks clean: I think the pixels properly being on a grid really helped it (I will admit that's not something I ever pay enough mind to for a jam).
I only encountered a couple issues: 1. it seems like the water stops building up at some point even though it's not leaking anywhere 2. I got stuck on level 8, where the blue shiny didn't shrink the other vine, even after I brought water to it.
