i got 2 ideas Firstly Why not make like most games and Open a talking function where you can talk not type ok second Why not add A xbox Supported Walking and Button usage Thingie Where you can play with a xbox remote say on a pc ? Then it will have a smoother walking Way Where you dont have to click on a block to walk you can actually walk and when you use the xbox You can just walk into the door Then you will enter and exit or use the lift and Just pick a floor
