This is so wholesome, it's hard not to love.
It does kinda kill me inside that I can't get the medals I missed, but the quality of the art more than makes up for that. If I could nitpick about one thing, I think the ability to close out of the art should also be mapped to the space bar, but other than that, yeah, great game that I certainly don't mind coming back to everyday.
EDIT: With the ability to close out of the art now on the space bar, the nitpick part of my review no longer stands.
