My Opinion of undertale so far.

Undertale is an amazing game because it is rife with details, for example saving a loading will result in characters you've killed recognizing that you've killed them,

However, it goes farther than that, the characters in this game are sublime, and the writing is amazing.

The combat is a simplified bullet hell mixed in with rpg elements, which is nice.

also, papyrus is best husbando.

This game is an interesting one because it turns a fourth wall break into a game mechanic that extends across all of your playthroughs and can even permanently lock you out of the true pacifist ending if you play it like a normal rpg, toby fox did an amazing job with this thing.

this is what a lot of people truly want from videogames, games that challenge their senses and destroy their expectations by ignoring conventions, and toby's wildly popular rpg is so well made and well written that you'll easily overlook the simple graphics.
