HEYA!!! This is Undetale's Dogcheck. You can use it for your game too! i recommend it :D (make sure u check inside!) ,..(okay this lowky buns but hey i just started)
The dogcheck only works if there is a sprite, backdrop, or a costume is missing. or if u delete one of them while the game is running. (Don't delete Asset Checker, Dogchecker, and Missing Asset)
