This is a beautifully crafted game.
It took me awhile to figure out what was going on, such as, needing to click on the bud to open up it's movement arrows. Sometimes I would accidentally trash can a growth option because I thought I was clicking on it to select the action (my fault). Once you figure out how the game works...it's really fun and interesting. I like the way you've integrated the game jam theme. having the vines 'super nova' is just a very creative idea to unlock the complexity of the game play.
Well done. I think this could be the start to a full game.
