Martlet's Fun Adventure! Demo

By Roebloz
   

Martlet's Fun Adventure is the simple and fun family-friendly platformer fanhack of Sonic the Hedgehog 1 on the Sega Master System, starring Martlet from Undertale Yellow, where nobody has to die! (Except pretzels. Loooots of tasty pretzels.)

The premise of the game is simple, taking place a few years after Undertale Yellow right before UNDERTALE starts, with Martlet going on a fun little adventure to find Starlo and Ceroba, who are mysteriously not showing up for brunch. On top of that, the Underground has been thrown into a state of civil unrest after an attack on New Home from a group of Vinefroggits, powerful, seemingly brainwashed Froggits with prickly green vines coming out of them and floral patterns, who seem to want nothing more than to terrorize the Underground and cause a civil war, with monsters already fighting among themselves confusedly, accusing each other of controlling the Vinefroggits. And as if that wasn't enough, our precious birb hero keeps losing her diaries, now having lost one for the sixth time this year.

In order to investigate and possibly solve all of these mysteries, Martlet will have to explore many areas of the Underground from both UNDERTALE and Undertale Yellow, braving the freezing cold of Snowdin, the rushing waters of Waterfall, the malfunctioning robots of the Steamworks, face the hot temperature of the Dunes, avoid falling into the CORE and finally, hopefully find the one responsible for all this in the Ruined Garden underneath New Home. She will also have to avoid or kill the various confused monsters, coming from both UNDERTALE and Undertale Yellow, and at the end of each area, face off against one of the deadly Vinefroggits and their magically summoned Petalfly ride, and survive their various attacks.

Will everyone's favorite clumsy bird be able to save the Underground and her friends, or will the Vinefroggits and the mysterious entity controlling them have their way and cause the Kingdom's crumble with terror? There's only one way to find out...And that's to play!

Also available on itch.io, with occasional newsletters and eventually updates! https://roeblozgames.itch.io/martlets-fun-adventure

  • r/MartletAppreciation and r/UndertaleYellow Members: Suggestions, Feedback, Hype
  • Original Undertale Yellow Team and Toby Fox: Inspiration and source for many graphics, characters and ideas

GRAPHICAL CREDITS:

Graphics were manually downscaled, edited and tweaked by me and Irenepunmaster to fit in the game, and come from the following sources:

  • Undertale Yellow by Undertale Yellow Team: Design and graphics for Martlet, her handbook, the Steamworks, Frostermit, glass shield, extra decorations and graphics for Snowdin and Waterfall, Petalfly, Vinefroggit's vine, and many other assets
  • UNDERTALE by Toby Fox and Temmie Chang: Design and graphics for Flowey, the DETERMINATION font, Game Over screen, title logo, Snowdrake, Vinefroggit's base (Froggit), main Snowdin and Waterfall graphics, and many other assets
  • DELTATRAVELER by RynoGG: Flowey's side sprites, Snowdrake reference
  • Others (exceptions): Pretzel graphics based on this DeviantArt pixel art by PixelDonutofCanada91, (badass username) title screen's copyright date and credit font based on the one from Generations 1 and 2 of Pokémon, (Where they serve a similar purpose) Super Mario World's grass tileset was used as base to make the shape of the main ground tiles and corner tiles, Instruction Booklet Underground illustration by FlaringK

Do note that due to both Undertale Yellow and DELTATRAVELER's nature as UNDERTALE/DELTARUNE fangames (With this hack being a fangame of a fangame), they also used many assets from those respective games, altered or not. The credits listed here are only from where the assets were explicitly taken from for use.

In addition, the only things listed here are assets exclusively featured in the demo; Later, currently-unimplemented areas will not be taken into account. This is also not an exhaustive list, but most assets were taken from these three games, with any exceptions listed.

All music was manually adapted for the Master System by Amilgi. Similarly to the above situation with sprites, Undertale Yellow remixes some UNDERTALE tracks, and this only includes tracks featured in the demo.

I'm not familiar with Undertale (haven't played it yet), but I can see that this hack is sweet and nice, even taking in account the... unique physics of the Sonic SMS engine.

Still struggling at the Waterfall boss, but unlike most previous 8-bit hacks, this one is not making me ragequit yet!

Also... yum, pretzels~!

Roebloz @ 2024-09-28 12:06:07

Yum

Selbi @ 2024-09-28 14:13:03

If we had a trophy for Most Cozy Hack, this one would win by a landslide!

Jdpense @ 2024-09-28 16:33:08

Out of all the 8-bit hacks, this one impressed me the most!

Though with that being said, it feels surreal for Marlet to attack her own kind.

Roebloz @ 2024-09-28 19:37:29

Thank you! Though, as I said, you're not forced to attack them, you can just avoid them! (Aside from Vinefroggits, but they're possessed, so you know)

Netthecybernetichedgehog @ 2024-09-28 18:39:35

Man i Love undertale yellow and then i dicovered that i downloaded imiaditly

DizzyAC @ 2024-09-28 23:55:32

This has to be one of the most charming games I've played possibly ever. I absolutely love this as a return to these characters from UTY and I especially appreciate the detailed booklet written with it. Spent the entire game attempting to dodge every enemy I could. My only hope is that Dalv gets included in the game in some shape or form. Otherwise I'm very much looking forward to the full release!

Roebloz @ 2024-09-29 14:03:12

Good job beign a pacifist! I'll try to put Dalv as an easter egg somewhere, though he's not really involved in the story.

diablo666 @ 2024-09-29 09:03:09

It's a beautiful job. I was interested in him. I am waiting for the full version

Roebloz @ 2024-09-29 14:02:46

Martlet's a her! But thank you
