Grow your crop tall enough, to reach the second world. It will need water, and it will need fertilizer...

Game pad supported, otherwise WASD to move and SPACE to jump. Catch the rain drops, deliver them to your vine. Jump to the breach in the sky to win.

Slain people will be replaced by the next generation, and turn into fertilizer; but be wary of the fire, which will consume the first world...

Note that this game runs much better under Chromium than under Firefox; but in theory either one will do.
