Headcanon that the reason the trashcan lid blocks bullets is because the Steamworks higher-ups decided that instead of teaching all their employees proper lab procedures, hazardous substance protocols, etc, they would just make the trashcans indestructable and went “yep that should be enough”

Howdy!
As you may know, recently, Undertale Yellow was at the forefront of a discussion around music copyright. This was an unexpected event, but we wanted to clear things up as soon as possible, do right by the rules, and put an end to copyright claims on UTY-related content.
Since then, we have been in talks behind the scenes to resolve these issues. Thanks to the cooperation and hard work of Toby Fox and Materia Collective, any YouTube claim that occurs can now be disputed and released - much like how UNDERTALE’s music works.
We thank you all for being so passionate for UTY and its music, and hope this situation paves a better path for fanworks of the future. Much love đź’›
Experimental Patch 1.1.0
First, we would like to thank everyone for the incredible reception we've got for UTY đź’› it's been surreal in the best way
We do hear your feedback though, and have worked to address what we can in a new patch for Undertale Yellow. Please be warned, we haven't been able to test everything with this patch, but we're confident it should work in a normal playthrough
Thank you once again for playing and giving feedback! We realize these are not all the issues that have been brought up, but we will continue to work toward improving the game!
You can download Undertale Yellow version 1.1.0 on Gamejolt!
**This new build will recognize any ongoing save, so just make a new folder for the zip contents or replace the old ones and you're good to go
