This is my newest game is still a work in progress, but it’s slowly coming together. I’ve already coded the red, blue, and green SOULS, and I’m currently working on yellow and purple. Each SOUL has its own mechanics, so a lot of the work has been making sure they all feel different and actually fun to play. (It’s been hard trust me) Right now, blue is by far the easiest SOUL. It’s playable and works as intended, but it definitely needs to be harder, and I’m planning to rework or tweak it in the near future so it’s more interesting. Green and red are in a better spot difficulty-wise, but there’s still balancing and polish to do across the board. There’s still a lot left to finish, but progress has been slow and steady, and I’m happy with how it’s shaping up so far, and you can press {Menu} to view which battles you’ve beaten. I should mention that this is based of @Nugit’s project, [fight a guy](https://forum.makecode.com/t/fight-a-guy/40499) (I know him IRL) And without further ado, here is the game! > **[All Undertale SOULS DEMO](https://arcade.makecode.com/91281-35590-99380-98377)** > > cool game > **Previous version** > > [https://arcade.makecode.com/S16187-91850-76298-96361](https://arcade.makecode.com/S16187-91850-76298-96361) P.S sorry for going on a yapfest. ---

An update has been added!!! I have now added - I-frames, - Slightly nerfed red SOUL - Slightly buffed blue SOUL And, that’s it! I know it’s not a big update and most of you probably don’t care about this really, but still, I’m proud of it, and if you have the time, please play it, tell me what you think, what I should add / remove. Also, if anyone can make a jumping system for the blue SOUL like in the actual game, that would be peak. > **[All Undertale SOULS DEMO](https://arcade.makecode.com/92166-07398-33758-59146)** > > Made with ❤️ in Microsoft MakeCode Arcade. ---

Looks like that [Undertale Remake](https://forum.makecode.com/t/undertale-arcade-devlog/32377) from a couple years back is still possible. ---

Woo Hoo!!! Another update!!! This time I have added - Buff to blue SOUL. (Again) - First attack of purple SOUL Again, if any one could help me with a better jumping mechanic for the blue SOUL I would greatly appreciate it. (if anyone’s wondering, I want it to be so that the more you hold the up button, the higher you go, that caps at a certtain point.)

Hey, no prob. 👌 Keep working on this, its looking really good so far! Perhaps we could make a Consept boss once this is done? I’m good at writing all the outcomes for Diologe, along with being decent at pixel art, I just kinda struggle on the coding side of things. One other thing, I would suggest using Richard’s [Mini Menu](https://forum.makecode.com/t/arcade-mini-menu-extension/14368) extension instead of the story extension for the options. I think it might better suit an options menu rather then the diologe one you have currently. ---

I used @Danny_Devention idea and replaced the story extension with the Mini menu and added a cool background because I thought it looked kind of bland. > **[All Undertale SOULS DEMO](https://arcade.makecode.com/S07215-69350-48100-35624)** > > Made with ❤️ in Microsoft MakeCode Arcade. ---

if you want i can make music for the ultra boss that danny suggested (or you could use penumbra phantasm Reyce mix) ---

if you have spare time, could you make music for just the normal things, as we probably won’t get to the ultimate final boss for a while ---

Yeah i’d rather we go adapting original tracks. Maybe if we do decent enough on a Toriel adaptation we can branch out into other AU’s or even franchice cross overs. ---
