Yep, Frisk is still the first fallen human here! You play as Chara. On the other hand, "Determination" swaps with "Hope". Which means, "Hope" is the core trait of every human being. Chara benefits a lot of hope and possesses the soul of "Courage".

Yep, this is the "wind" replacement. Additionally, Waterfall swaps with the Ruins, more specifically, the Garbage Dump swaps with the Starting Point and the mushrooms swap with the golden flowers. If you fall onto them, you'll find yourself in a beautiful and serene atmosphere of the sanctuary... well not when you're in the start of it since there'd be garbage all over the place. And just as importantly, have "faith" in yourself to the end!

*Welcome to the SANCTUARY, young one.
*The archeological remains of the subterranean.
*Prior to being flooded, many used to dwell in these ancient relics. 
*However, today I am going to welcome you...
*...to your "New Home".
*Err... you may wallow in its unusual atmosphere.
*Though I hope it will not get you... soaked to the skin, hohoho.

*The water rushing down from the unknown fills you with HOPE.
*Go ring your first bell!

As stated in the previous track, the reset bell from waterfall swaps with the save point. If you somehow die, you'll be brought back into where you ring your last bell! Related to the sanctuary, the little mouse from everywhere swaps with the spiders from the bake sale location. If you like cheese, consider buying them for only 7S! And just as importantly, have "faith" in yourself to the end!

Two of the mercenaries from the CORE swap with the two of the amalgamates:
• Madjick - Memoryhead
• Knight Knight - (Endogeny)
• Lemon Bread - Reaper Bird
• Dragon Monster (Unused) - Crystal
The "amalgamates" here dust instead of melt. For how it works, imagine a dusty corrupted entity. Once disintegrated, they return to its monstrous state. This is caused by the effect of too much HOPE injected into them along with a forsaken experiment.

So I suppose this is basically the first introduction to WARPEDSUN, the deltarune replacement of the swap universe that I made. "Before the Story" plays for both games. And before we actually begin to posting WS tracks, WS is a team's AU (just like how Toby Fox made his own team for deltarune), meaning I won't be the only person to work on it. "What about PROSEMOOR?" Don't worry, I have a few songs done for PROSEMOOR and will continue uploading again later. On the other hand, WS swaps dark world with other dark world instead of just swapping characters all over again.

Underswap belongs to the community
However, somewhere in an alternate universe... Temmie was the creator of Underswap

In all seriousness, this is my take on Underswap.
You can call it Temmieswap, Moonswap, "underswap", or even lowercaseswap (thanks to Slick Silver)

Beforehand, this is in no way related to "Legend Behind the Chasm". That AU stays as an ambitious "Underswap-inspired" AU project with a particular Temmie's aesthetic. This is all the more the fun little reboot of my old "Temmieswap" official soundtracks. While this garners some of the canon/classicswap aspects, I've decided to add a little bit more of creativity and spice some things up, but not to point where it goes "very original" which is not what I'm aiming for. Roles might change in the future, but for now, it's still a heavily work in progress. And final note, I'll only swap "Undertale" motif with another "Undertale" motif. So there's no other Toby motifs, let alone Temmie's
