Extremely creative use of the theme. I really like the Earthbound/Undertale style of having a cute presentation overlaying discreetly darker and creepy moments. The use of difficulty and accessibility options for problem solving really threw me for a loop until I really played around with the settings.
I do wish that there was a downloadable executable though, since it seemed to lag pretty hard on my laptop's connection, which caused me to walk into walls for several seconds repeatedly due to delayed inputs. Apart from that though, it's a cool concept and I like the tone of the writing!
