Deltarune: Chapter 3

A genre mashup that isn't really like anything else I've played. It's a 2D zeldalike, warioware-inspired, guitar hero-esque RPG. That's probably never going to happen again. Pretty cool. My biggest gripe is that the best parts of this chapter are locked behind an esoteric series of events that no player would ever encounter without a guide. And if you missed this incredibly intricate sequence of events then you have to play through the whole chapter again (not fun)
