Simple proof of concept lava map featuring:
Periodically rising/lowering lava
Slight screenshaking at each movement start
Damage to units (excluding air) touching lava (includes a small splash+sound effect)
Big thanks to Dino29 for helping to figure out how to make it work.
Nice. There isn't much competitive use for lava, though. It seems more like a way to pointlessly stall someone.
cool stuff.
