Undertale Review

A game whose central argument is that you never have to kill anything, built by one person who wrote the code, the sprites and the soundtrack. The technical bar is low and the design bar is absurd. Every encounter is a bullet-hell puzzle with a nonviolent solution, and the game tracks not only what you did but that you reloaded to undo it, which turns the save file into a moral document rather than a convenience. That conceit powers the two endings that matter: the genocide run is deliberately miserable to play, and the pacifist ending is gated behind mercy you have to actually mean.

Sans and Undyne get boss fights that break the game's own stated rules, and Toby Fox's score does emotional work the deliberately crude sprite art cannot. The role-playing parody surface is funnier than it needs to be, but the jokes are load-bearing, softening you for a final act that argues directly with the player holding the controller. Short, cheap and structurally unforgettable.
