1)I don't play for very long but I noticed that there is no building physics in the game, for example, if you put two walls at the top and destroy the bottom, the top wall will still remain in the air - I think it would be better if the walls of the 2st floor are destroyed. has nothing to hold on to ,2)I also suggest adding a new type of explosive, for example, for each type of wall you need an explosive suitable for the wall for example on a stone wall dynamite on metal c4 something in that regard
