This is a really really great game! Is this pico-8? It's really quite well done. I love the way you introduce new mechanics and they all feel very nice to use together. The sword and the vine were quite unique, and I especially liked that the sword had multiple uses (and none of them were combat hehe). Only thing I would mention is that if you're in the air you can drop multiple seeds and grow a whole bunch of vines at once, but that's not really an issue because the rooms were so well designed around the abilities you have. I'm very impressed with the pacing. And the art was nice as well. Beautiful game, super fun, I'd love to see more.
