12/18/2025 // SWAPPED MYTH Dev Update


Hello everyone! @Neon-Gr33n here!

As I've mentioned in a few previous posts on my profile, this *will* be a shorter dev update compared to our next full-length devlog, but I wanted to update y'all a bit on where we are at, I won't dive too deep into details just yet as I intend to save that for our next full-length devlog.

With the help of @aaratnuu-jp , we have the majority of the game translated into Japanese, which is one of THREE languages Swapped Myth will support on day 1, the other two being English and French. We did a full overhaul of our localization system to make this possible.

Below are some screenshots of the game taken after setting the language to Japanese

(Translation: "Welcome to the Underground....")

(Even our naming screen was translated, like in Undertale, you can switch between Hiragana, Katakana, and the Alphabet!)

The battle system is also in a near-completed state, there's a few revisions we intend to make, such as making ACTing a bit more flexible to our needs, and adding the MAGIC mechanic in, but the basic 4 buttons from Undertale all work as intended and you can spare or slay enemies. but remember- violence has consequences.

(Also, the battle background shown here is a placeholder, and will be replaced in the near future!)

We also launched an official website for SWAPPED MYTH (our next Devlog will be posted there in addition to here!), and created a YouTube channel where we have begun to upload the OST, you can check it out > here < ! Our composers have been making some absolutely beautiful music for this game.

As far as writing goes, we've gotten through about 60% of the story for the demo, and we currently have a few playable rooms!

I don't really have much else to say, but I'd like to point out that we are still accepting new members for Team Mythical! Want to help us out? Feel free to apply here! Whether you're an artist, a programmer, or even a musician, feel free to apply! If you don't have discord, you can also email me at [email protected]

With that all being said, that is about all for this dev update, like aforementioned, I'll go into much more detail about everything in the next proper devlog, this post was made so that y'all aren't left in the dark, and have at least some sort of update!

We are on a temporary hiatus from development until the end of the holidays (until the 2nd of January!) but trust me, once we're back, we'll have plenty to share!

Thank you, and remember to stay determined!

(Also, happy holidays to those who celebrate! <3)

Are you really still going to try to kill him? kill someone that cannot defend themselves?

Made some more progress on sans' sprite, once again, a tad new to pixel art, criticism and suggestions are appreciated <33

Undertale, but nothing's wrong.

Working on a sans sprite rn- this is a VERY early preview, it is nowhere near done yet lol, still some things I need to add, and improve on, like the scarf, the shoulder pads and making his jacket more of a hoodie/armor hybrid

Feedback appreciated <33
