Spent this week making a little Worms/Scorched Earth terrain demo. Tried making one of these with my first ever #pico8 project and ran into massive performance issues due to using pset.

This uses tline and a 2D array of vertical slices. Destroying the terrain earth shrinks a slice, or cuts/slices it into two. Perf is good, as terrain is destroyed, there are more slices, but less to draw! Second gif shows this in action.
