Really great. Nice mechanics, ideas and level design, and the gameplay is very polished. I would love to see this game expanded upon after the jam. I really liked how every plant had multible uses, and every puzzle was fun to solve using the tools given. The game was very inituitive too, and apart from the controls, everything sort of just made sense without an explanation.
I did encounter a few bugs though, and the text boxes closed a little too fast i think. You probably already know, but in case you don't these are the bugs i found:
Being stuck below ground (near stairs)
Climbing-plant stopped growing prematurely.
Player character rotated slighty.
And a lot of seams when i moved around. (This should help https://tiled2unity.readthedocs.io/en/latest/fixing-seams/)
