Really awesome game, managed to pick it up even after skipping the tutorial easily! I would love to know how you got the drawing recognition system going :)
Drawing recognition was handled by the "$1 Unistroke Recognizer" which has a few implementations you could probably find! Glad you were able to figure out how to play, it's been confusing for some and we probably could've done a better job at showcasing the mechanic. Thanks for playing!
