My 10y old mini me finished Cuphead... Playing on keyboard with only his left hand!?

My little insane 10y old mini me just refused to use a controller or the normal keyboard settings, he claimed that it's easier to just run 'n gun with one hand only and he has proven himself right as he, after 34 hours, finished the game completely.

I am stunned!

Now let's see if he can do the same by using a dance pad!
