CONTROLS:

Left Click (On Green Button) = Fire Rocket

Right Click = Redirect All Rockets

Rockets get more powerful the more they're redirected. Launchers have a longer cooldown the more rockets are already out. Rockets disappear if they go too far offscreen. Trash deals however much health it has left as damage to your planet.

I would have liked to get an in-game tutorial in, alongside a proper title screen, but alas. Curse of time.
