This one was a lot of fun. I got up to wave 10, to anyone gonna play this: don't immediately spend your light points. save them as long as possible and only use them when it's time to heal the tree.
It met the theme super well, and had no bugs or anything glaringly wrong. The quick cutscene in the beginning did a lot to set the stage. Definitely get points for the effort there in my book. Particles were cool. Over all very enjoyable game.
