I like this game a lot! There are a lot of plant types, upgrades and enemies! It's a very good tower defense experience! I loved how the enemies progressively got harder and more mechanics got introduced, this game has a well-built progression system! Heck, even enemies started to come from the sides to the tree, completely ignoring the pre-existing pathways (I'm not sure if this was a bug or not, but I love either way!).
The only thing that I got me confused a bit was how the new lanes just popped up from nowhere, I didn't realize instantly that they appeared and played some rounds without realizing that.
Also, some of the plants felt... pointless? Like the daisy flower that shoots in 5 directions, I don't think there is any place where this can be useful, at least on the map you made.
Oh, and one final things, when planting the plants, they move get pushed around a little bit for some reason, is it because they are planted on a grid? It just felt awkward to me…
But other than that, this game is really fun! Great job!
