I finally was able to play your game, I'm glad I remembered to!
This concept is so cool! It's a fresh idea to the tower defense genre that feels super cool! The user interface is pretty rough though... each time I click a plant is moves away from my cursor and takes up time. This is compounded by having to click every time I want to plant something, as opposed to clicking once and planting multiple times.
The game is too easy and doesn't offer much more after the first few nights (tangleweed op). All in all, I really enjoyed this though! Def. made it to my top 10 of the jam. I'd love to see more. <3
