The 2025 build is the most recent one, and the others are just to show what the project could've looked like if I was lazy enough. I'm glad I decided to rewrite the engine, because the other two builds actually suck.
Please note that we haven't completed much of the 2025 build, but there is quite a bit more content than the other two builds.
Enjoy whatever content you'll get out of the build.
(By the way, read CONTROLS.txt. It shows how to switch rooms in the build.)
Keep in mind that these builds can't be navigated without debug controls, so you will need to follow these instructions to activate it:
For copying:
[General]
LaunchDebug="1.000000"
2025 build:
Go to
%localappdata%\RetoldProphecy
(If you don't have this folder, you have to boot up Chapter 1 at least once. I don't think the launcher itself creates this folder, but I could be wrong.)Open
game.ini
Put this in the file:

2023 build:
Go to
%localappdata%\swidevs_deltarune_engine
(If you don't have this folder, you'll need to boot up the 2023 build)Open
deltaengine.ini
Repeat the same process as you would for the 2025 build.
Alternatively, if you know how to use Undertale Mod Tool, you could just put this at the end of scr_setup in the 2025 build (or right before the game calls room_goto_next in rm_init (or room_init, whatever it's called in the build)):
global.debug = true;
Or you could put that literally anywhere that would activate debug mode. Step event of the controller object for the build (obj_global_controller for the 2025 build)
If you datamine, you'll find some of the shitposts we've shared for the current iteration of the project, as well as some we haven't.
