im nowhere near done with this but in this game, u gotta reset the game by refreshing the page( u can fall of the map) 

youre a capsule and you gotta defend against a horde of mouses that are gonna screw with your clock tower, use E to repair circut  that the mouse breaks, and use spacebar to kick the mouses out of the clock tower 

E - repair circuit/Feed battery
