HIDDEN SECRETS

I'm not sure if this one's as effective as the original, but I had a lot of fun composing it, gave me a chance to try out new stuff.

005 - Ruins

The unused version of the track "ruins", Reused (?) in the Undertale: Bits and Pieces mod.

Composer: Toby Fox

Ruins Piano

Back with another track!
I basically got hired to be a composer for another Undertale fan-game! This one is called "Don't Forget" (it can be found here: http://gamejolt.com/games/undertale-don-t-forget/150752) and I've made two tracks so far for it.
The first one is this one, which is background music for the surface village area in the game, which I call "Chara Village" :3. I originally titled it "Not-So Homely Home" since first it's a remix of the "Home" theme in Undertale, and second it was going to be used in a broken and scary home area at the end of broken and scary ruins area in the game, but RickyG (the creator of the game) decided instead to use the track for chara village. He also renamed the track to "The Village" when he put the track on the Gamejolt page about an hour ago, so I put that title too.
The other track I made for Don't Forget is probably the next thing I'll upload here, and I'm pretty proud of the track. It's most likely not going live for a while, though, since it contains spoilers for the final boss of the game, who's coming in the next update.
That's about it! Hope you enjoy the track!

Don't Forget M.D OST - The Village / Not-So Homely Home

A seemingly perfect paradise for monsters where beautiful light just like the sun keeps the green grass warm, and lets the flowers bloom. A place where all different kinds of races get along and find a common ground.

Fun fact: This song uses motifs from other songs I composed by hand.

Realmway - Safehaven

"My name is John Webdings. I just got out of law school a few years ago. I work for the Stormedout Police Department. I've been assigned to take down a serial killer in this city named Sans. It's been rumoured that he's associated himself with a massive organized skeleton-exclusive gang known as the Wingding Mafia. If I can stop the suspect, Sans in his tracks, I might have a better chance at shutting down the rest of the organization. I work for my partner, lieutenant Kop-K who is helping me track down this guy. If Skeletons don't have a bad enough reputation in this city, he certainly makes it worse."

Comissioner Skellington is watching the news broadcast on the Police Dept. television during his break:

"Hello! You're watching Stormedout Info live! I'm Larry Presto, your skeleton anchorman for this morning program! For the first story of today, violence on the streets continues as the Wingding Mafia continues to rob people on the streets. In other news, we have a weather report to cover. Over to you, Jake! How's the weather out there"

"..Thank you Larry. As you can see, it is a pretty windy and rainy day in this city as usual. Having such dense clouds underground will give you this kind of weather. We're expected to get some hail and even some brutal snowfall by this weekend. Back to you, Larry"

"Thanks for that report, Jake! This is Larry Presto! Signing off. Ladies and gentlemen of Stormedout, have a wondnerful weekend."

005 - ruins.

Long ago, two races ruled the Earth: HUMANS and MONSTERS.
Once day war broke out between the two races.
After a long battle, the humans were victorious and sealed the monsters underground with a magic spell.
The rulers of the Underground did their best to keep the monsters' HOPES and DREAMS but...
Day after day, the rulers along with their children..
Vanished.
The underground was devoid of their HOPES and DREAMS.
Many years later...

Legends say that those who climb the mountain never return.

* I am BUTTERCUP! BUTTERCUP the BUTTERFLY!
* Do not be afraid! For I am the caretaker of the RUINS.

Flowey's encounter theme for Wonderful Idea!
Join the Wonderful Idea Discord Server - https://discord.gg/Vmq2rxM

Flowey plays a big role in the story. He will secretly follow us along our journey and often stop by to have a talk. His main objective is to convince us to embrace the "Kill or be killed" rule. If we don't listen and continue with a Neutral/Pacifist route, he will try his best to talk the enemies and bosses out of sparing us. He will also have a 75% chance to stop us when we attempt to flee.
However, if we do end up listening to him and start a Genocide route, he will fight along our side and help us kill the Monsters. He will heal us in every battle by dropping healing friendliness pellets and sometimes even attack the enemies himself.
-
This track will be remixed for each area - this is the Ruins version. It plays a few times during Neutral/Pacifist whenever Flowey appears in the overworld. Completely replaces "Ruins" theme on Genocide.

Here's some dialogue:

-Pacifist-
Howdy again! How's life treating ya?
Bet it's quite tough here and there!
Say, I've noticed no dust trail behind you.
Every monster left unharmed...
You're pathetic really!
You'll soon learn how fun and easy killing is!
Hm... actually, I have an idea!
I know how to make your decisions a bit easier.
No longer will you think about the choices you make...
I will make it very easy to pick the right path.
It's kill or be killed around here.
No monster should listen to your CRAP.
I'll make sure of that.
It only gets harder from now on...
Don't get too cocky.
See you soon!

-Genocide-
We're approaching TORIEL quite quickly.
You should be glad you have me on your side.
You wouldn't have survived if not for me...
Your best friend!
Anyways, no time to waste!
Let's keep going, partner!

PS: This was made about 2 months ago but I didn't have time to upload it until now. Sorry for such a long wait between new WI tracks, I'm renovating my room and I didn't have access to my PC. The next WI track will be big.

[Undertale: Hard Mode - Wonderful Idea OST] Ruins Follower

*Rest at last, human.
*For here, even despite everything... 
*All can be at peace.

Deepertale is an AU that takes place in the aftermath of a nearly complete Genocide Run. Alphys has hidden all the survivors in the True Lab. Flowey was the only one who got in the human's way and lived to tell the tale (and that was by escaping within an inch of his life). The human has chosen not to erase the timeline yet, and walks the dusty Underground while down further below the monsters cower in fear. Flowey takes the role of Mettaton, and his "Hotland" is a massive machine that delves into his subconscious. Here, the "resort," is a peaceful garden. The eye of the storm. The one place of calm inside of Flowey's mad mind.

Deepertale is considered to be a satellite AU of the Aftergore series, the Discord server of which can be found here: discord.gg/WbzykND

[Deepertale] Garden of Serenity

When Asgore, Toriel, Asriel, and Chara all mysteriously vanish, the timeline is directly affected. Papyrus becomes king of the Underground, Undyne becomes the "caretaker" of the Ruins, Sans stops being lazy (maybe), and more changes throughout. Hey, who's that little butterfly?
