Oh, it's not just you, a lack of proper oomph on my visual cues was bugging me a bit toward the end too. I'm thinking about limiting the distance of the rain drop spawning from the player, if/when I come back to this.
You can't put out the fires; the first world was canonically destroyed by fire. The idea is to grow the crop enough to climb it to the breach in the sky and reach the second world before that happens. Thank you for playing, and I'm glad you liked it!
