i like deltarune but unfortunately i always have to torture myself by having a guide open in order to extract as much dialogue and secrets as i possibly can. i understand that toby fox likes secrets and it's cool for the fandom to have these and meta stuff but personally it doesn't sit right with me, and i think it's genuinely poor design if i feel a compulsion to actively ruin the fun of the game.
also there's some slight polish issues like your custom keybinds not working on the start chapter screen. otherwise it's pretty much perfect. banger soundtrack, amazing dialogue, always keeping it fresh but never overstaying. i reserve the masterpiece title for something like disco elysium but deltarune might come close.
