>>2722well to start of with it's basically just a yume nikki themed earthbound fangame with a really cool story and cute furries. the gameplay is like a mix between warioware/mario and luigi and touhou 6, and it makes use of the medium in really clever ways (kind of like hotline miami) without being all "ooh look at me im hecking self aware and special!!!". also there's lots of secrets and obscure tidbits but in a cool way that doesn't impact the main story.
it also doesn't try too hard, unlike many new "quirky" earthbound-inspired rpgs *coughs in omori*. the humor is kind of timeless and well placed, there are no marvel one liners, and it has a really great midi soundtrack too.
i think you kind of need to play undertale first which sucks but the first two chapters of deltarune are free and save data can be carried over into the main game if you think it's good enough to buy.
but yeah really awesome game you should go check it out it's really cool and awesome i think
