5 stars: My son has autism and loves this and anything to do with undertale. This is his words now about the game I just love sans and papyrus but not floweey and mega flowerey. And also the songs are way cool I can't get them out of my head. I sing them to my mom all the time but she does not know much about undertale it makes me laugh. Also please make better bosses you can't really see them just your health. I will play this game everyday and if you update and make a better one I will buy it and play. Your fan down in the Arizona desert Silas Noah.
4 stars: Well, I love this game! It is very good time killer, great soundtrack, although I would like to see you add different music other than the Finale Remix. I would also like to see you tone down Asgore's fight a little. I can't handle the fire AND the tridents at the same time even on casual mode. I would like to see these changes happen. P.S., Also, please add a Mettaton phase!
4 stars: This is really cool! I love Undertale and this app remind me of my first time playing the game myself, nostalgia in a good way. And the music is fantastic! ^^ However, I have trouble with controlling the blue soul...I don't know if it's just me, or its the controls. Other than that, I love it! :D
4 stars: I loved everything about this fangame. The controls are a bit hard at first, but i managed it. All of the SOUL modes are bada55, especially green mode. But when i got to the end, there were only like 3 attack phases... so...
