friend of mine showed me something awesome and made me think

If I'm not being destroyed by collegework, should I do random voice requests again? I really wanna do some Dalv, Starlo, Axis etc stuff again and I miss it :>

Sorry for the long wait, but I finally done it. Here's a new sprite edit of Martlet running in all 4 directions. I'm happy with how this turned out, and I wanna thank @pkplague.bsky.social for helping me with this.

This game means so, so much to me. Thank you, truly.

A drawing based on the true pacifist ending of undertale, featuring the games cast (frisk, toriel, sans, papyrus, undyne, alphys, asgore) watching a sunset. Above the characters, there is text reading “thank you for 11 years”

I love music. Specially like soundtrack kind of music. Whether it's from a movie, TV shows, or video games, I love them. It's like when you listen to one of them, nobody is singing to tell you what is going on in it because you know what is happening. You know what I mean.

Still working on a Mart sprite (just a little tricky working on it, plus I got busy doing other stuff), in the meantime, here is an update on some "neutral" battle sprites of some of the main UTY cast.

Did some more edit changes to Martlet's battle sprites (both B&W and color), and I must say, I'm happy with how some of these turned out.

Still working on Martlet sprites, but for a small content break, here are some Dalv battle sprite w/color.

I experimented a bit with Dalv's cloak after seeing a comment on social media saying Dalv's cloak was "too well kempt." I want to know what you guys think.

Yo, after listening to Cutie Mew Mew Magic demo, I had a thought "What is someone used this, made a full chiptune of the official CMMM, and moded them into UYT game as the arcade music?" Someone do that, please. 🙏

Here are some sprite edit changes I made out of the new Martlet resprites, I have to say I'm kinda proud of how some of these turned out. If anyone wants to use they, you can. Just make sure to credit me if you do.

#undertaleyellow #UTYfeed #Martlet
Left: Old Martlet sprite. Middle: Update Martlet sprite. Right: My Martlet sprite edit. The changes of my Martlet edit is that I made her head more rounder, her eyes less wide, and I brought her wings closer to her body so they feel less diagonally. I wanted to experiment to see if she looked good with the old eyes or the newer (yet slightly smaller) eyes. Let me know which one you guys think is better. Left: Old battle sprite Middle: Update battle sprite Right: Battle sprite edit The changes I made for Martlet's battle sprite is I made her legs to be a little closer to eachother and not so far apart. I also made her pants look like more of jean pants and less of looking like sweat pants. I made her arms a bit more rounder in some areas. And I adjusted her head to the right by 1 pixel, so it doesn't look like she is shifting her neck to the side. Gave my Martlet battle sprite some color, using both some colors from her old overworld sprite and her updated overworld sprite.

Okay, after seeing all of the new updates on the Undertale yellow fangame, here are some of my honest thoughts about the major changes in this game.
