Very very fun! Also really interested in how the rating system is calculated overall. Can't tell if I got a 1/10 or a 7/10, but I'll just assume that it's a 7 and that I'm an artistic genius >:D
The ratings are calculated by comparing pixels in the textures.
Basically it just checks how many pixels that are white in the template are correctly colored.
About your drawing: Thats definitely a 7/10. Looks real good. Well done! :D
Does it in turn also compare the non-white pixels to the template then? Just really curious because I think it's cool game design. Your game is easily one of my top favorites of the whole jam.
