About this game

This is a game that includes many kinds of Undertale fangames.
There are many battles from different Undertale universes that were made by KYwoo and many other creators.

We can kind of say this game is collection of Undertale fangames!
If you don't want any of your work to be in the game, please contact me first.
But if you are a creator who wants to have their own game to be in this collection, you can always contact me to speak about it!
Have fun everyone!!

Special Thanks to Phakch & Paketa.

Ratings and reviews

It's a super cool game, one of the best Undertale fan apps I have ever played. Some issues I had were the controls not moving where they were supposed to. I put that I wanted them on the right side of the screen, but it ended up on the left anyway, plus it wouldn't let me move it to the other side in the customization menu. That's really the only problem I had. I can't wait for another update and more battles! Maybe we will get OG Swaptale Papyrus or a normal Sans fight.

The battles are pretty good, but they are extremely difficult to maneuver. And I like that the naming works the same as UnderTale, like with Chara being the true name, and other characters' names not being allowed. HOWEVER! Gaster crashing the game is completely understandable (as it does that in UnderTale & Deltarune), but River also crashes it!! IDK if it's a bug, a glitch or just some AU's rule, but please get rid of it. Thank you.

hey bro, great effort on that game. i have some points i would like you to consider: -the Scale difference between 1 and 2 is big a lil bit -the when i press "up" on some controllers, the soul (Aka the heart) moves Up right. i would like you to do an optional Emulate Controller or True/full control controller. have a great time. you did a great job
