This was such a lovely game! I like how surrendering control here is a relaxing and calming matter of acceptance -- I also like how my puff ball shoots up into the sky when I fire my seeds.
I will say that it felt counter-intuitive that the place where the last seed falls would be where the game ends -- I had expected it to be the puff ball, but I suppose that the seed makes more sense. There may be a way to convey this to the player by having the puff-ball decay with every seed you fire, until you just have one seed drifting down to the ground.
Overall, well done! One of my favorites! Keep up the good work!
