the arrows also work... but i also have a su suggestion... do you guys remember SNES 9x... @atmosgames since the arrows work, how about letting people use also the X key as the Click and the C key to jump... this way Lefty people could play using only keyboard, and also i'm sure many will enjoy to play as in retro games, and it would be easier on laptops and for Kids (my actual 9-year old kid suggested me that)
