Really nails its adaptation of an 80s/90s Japanese media aesthetic with how violent yet twee it is, and a super fun layout balances the energy perfectly with some of the most skilled difficulty scaling of the 2.0 era of demons. Some sections are pretty visually basic due to the object limit of that era, but I'm perfectly content with InsanitY being Not Ugly at its worst, especially given how many levels just completely fell apart when their creator sniffed the object limit back then.
