Really enjoyable game. I could tell there was a lot of thought into the level design. There were enough hints that it wasn't too difficult but also some technically challenging spots that made it fun.
My favorite level was the first one where you had to figure out that the water could create a bridge to get over the tall wall. Games that have a seemingly simple mechanic, but take it to the next level are really special.
My only critiques would be that I felt the number of seeds felt like they were too limited and didn't allow room for much error. I found myself getting past a tough spot using a lot of seeds and water to see that there was more platforming that required resources I didn't have - maybe just adding more resources allow for error. Also I felt strangely slippery on the plant growth. I wanted to feel more firmly "planted" but it's not a biggie.
Overall, a very fun, good-looking game with a very unique and fun mechanic!
