To move you have to press for a long time, and you cannot move things on the UI side, this is a problem with the engine that I use, if you are not able to click try to move the camera, because sometimes the buttons overlap , if the npc is not spawning try to move the constructions a little bit, and the webGl version has a bug that the npcs don't move, try to download version 0.3 which is an old version in the link that is in the warning area, I'm done to play your game, I really think your game will win
