    i was in a really dark time in my life, then i ran across this video- and it reintroduced me into undertale. undertale is honestly one of the biggest comforts for me and i’m glad i got into it again- because it helped me get out of that dark spot. thank you:)

    Yeah, youre right with it, when you said, that most viewer want to see the "right" way. I think i didnt find even one blind LP with genocide first to get the different endscene in the good run. that would be interesting to see from someone who is really interested in the story. There were a lot streamer/YT who played it just for the views and didnt even understand the obvious stuff.

    Hey Jack, please, I am begging you, check out the Game Omori. It's a game in the style of Undertale but with it's own style and way of telling a story of love, hate, tears of joy and sadness, and so so much more. And don't just take my word for it. Just wanted to rally that thing to you. I hope it reaches you. Thanks for you hard work over the years

    It's strange to see Undertale on this channel again...... bc the Undertale series was the reason why I started watching Jack and I'm not dissapointed xD Also I still love Undertale so much, even if I'm not too active in the fandom anymore. But thanks to that game I made many friends and even visited america for the first time for a small Undertale convention. Seeing my favourite RSclubr playing the game again that made a big, positive impact on my life.... that fills me with determination!

    At 24:50 he asks where the third frog is... what i discovered in my play through is that if you kill one of the frogs in genocide run, no matter how many fresh saves you have, that frog is gone. Another great example of your actions having consequences
