v.02f Single Player & Critical Fatal Error Fixed

[b]PLAY SINGLE[/b] - Added single player mode for solo players, which is no longer multiplayer. Have fun. [b]CRITICAL FIXES[/b] - Fixed the "Fatal Error" problem at the end of the game. - Fixed the "F" Key bug that prevented us from being able to open and also using other items even if we were away from the garage doors. [b]FIXED & UPDATES[/b] - Fixed a bug where the exploding zombie could not dash in the acid field. - Now your character will automatically stand up when you start running. - We created a balance system for our game, because when the crowd played the game, there were too many zombies and the environment became chaos. Our game now flows in a more stable, fun and calm way. -Fixed a bug that prevented the dynamic resolution system from working.
