Thanks for fixing what i commented a few days ago!!! I'm loving the map rn and the controls. I'm getting used to it. Maybe for this playtest, you could add a deathplane somewhere under or around the map to stop infinite falling?
For some ideas, i like your multiplayer concept, but i got a few more!
-Time trial
just a level or course with tight gaps in the walls or enemy turrets shooting you (or both), and 2 or more players race to the end
-target
basically have a target (house, car..) in a big map and the players have to blow it up, but it takes more than 1 hit.
then for not multiplayer, im sure an exploration mode would work well. maybe this is too detailed for a game like this, but these are only thoughts
