Yeah, I kind of find it funny to watch them fall into the ground. I am currently polishing the game, and I'm thinking of having the explosions push objects and civilians aside one tile. While I'm writing this, maybe I should go overboard and have explosions push them far away? Maybe kill the civilians if the grenade blows up on their own tile, but push them if it explodes beside them.
Yup, the doors are a bit unclear at first. Maybe we will add another explanation screen for them.
I also improved performance. Some assets were copied unnecessarily, and in the version submitted for the jam, grenades don't really despawn, after exploding they stay in memory and just not being shown.
Thanks for the comments!
