WASD to look around, click to put something down, space to remove something, numbers to select a hotbar slot, press the three dots to go into your inventory and to add an entity to a hotbar slot, hover your mouse over it and press a number to assign it to. g to enable/disable grid
this is kinda useless as of now, I will try and do something with it to make it more useful though. For a smoother experience you should run it here: https://turbowarp.org/490693157?fps=60 Update 0.1; now it only renders the on-screen area instead of the whole map, almost 10x more efficient
