PEAK FUCKING GAMING HOLY SHIT!!!!!!!!! Undertale is my favorite game as you can see by my profile, and this game is basically re experiencing the feeling of playing Undertale for the first time and I couldn't stop smiling the whole way through :')) I'm happy how original it also is compared to a lot of Undertale fan games, instead of just re making some dialogue and story progression Undertale Yellow takes you on a completely new adventure with new locations, a new cast and lore to sink your teeth into... this sort of story telling really helps it blend into Undertale as a possible prequel, since if you take a genocidal route for example the only characters you can harm are new ones that don't show up in Undertale canonically. This is gonna be an annoying lore ramble for a bit, but they basically just made the game basically be able to be canon in the universe, which I enjoy quite a bit (and also will be headcanonning as canon personally from now on TRY and change my mind bitch)

EASILY the best Undertale fan game I've played, and honestly probably the best game I've played in December all together. It's free on game jolt please if you're even slightly interested go download it and show the developers some love <3
