Deltarune: Lightners Live Plus

Welcome to Deltarune: Lightners Live Plus, a fangame recreation of the rhythm game from Deltarune Chapter 3!

Scroll down to the bottom of this description of the downloadable build. You can use the Itch App to get auto-updates if you want.

Here's the link to the Custom Map Guide

Here's the link to the GameBanana page, where you can download and upload custom maps

Deltaurune: Lightners live Plus has maps of most of the main tracks from Chapters 1 and 2, as well some bonus preview and unused tracks. It also has custom map support. If enough people are interested, I'll be working on adding Chapter 3 and 4 maps in after that comes out too. If you want more info on updates, follow me on Bluesky and Twitter, I'll be posting about this game on there. Also check out my youtube :) All of those are linked below. If you enjoy the game, feel free to share it if you want, including recording/streaming on YouTube/Twitch/wherever else if you want to! (also feel free to let me know, I'd love to watch!)

Controls are mostly the same as UTDR in the café. In the main rhythm game, the same controls as Deltarune's version will work as well as additional options: A&D, F&J, S&K (or any combination of those you want) or bumpers/triggers (on controller). To exit a map, press C (Y/Triangle on controller), you need to hold it while the map is in progress to prevent accidently pressing it. F4 (or Back/Share on controller) will toggle fullscreen. Holding Esc/Select/Options will close the game (mainly useful in the downloadable version, although it will still work on the web version). Controls in menus will generally be shown on the bottom of the screen, updating depending on your input method (keyboard or controller)

FAQ:

Q: The notes aren't quite synced up with the music, how can I fix that?

A: There may be some latency depending on your setup (browser, device, input method). However, the game can account for this! There should have been a message telling you this when you the first time you booted it up, but if it's been a while and you forgot: to set this up, talk to Swatch in the café, and adjust the "Latency Offset" value. You can press C(/X/Square on controller) in that menu to load a map that's just a metronome with notes on the beats, that will let you change the value in real time so you can hone in on the perfect value for you.

Q: I'm having problems on Firefox, is that just me?

A: Unfortunately the game has some big issues on Firefox, the map just doesn't load sometimes (or always). I strongly recommend using Chrome/a Chromium based browser for this game, sorry.

Q: The game is lagging a lot and/or shows a warning about lots of lag, what can I do about this?

A: This can be caused by graphics acceleration being disabled in browser settings, try turning it on. To do this in desktop Chrome, click the three dots in the top right, then click settings. Then go to "System" on the left bar (or search "acceleration"), and turn ON the setting labelled "Use graphics acceleration when available". It'll probably be similar in other browsers (although again, Firefox is not recommended). You can also try the downloadable version, which should have better performance, causing this to be much less likely.

Q: So this is a browser game... if I open it on my phone's browser will that work?

A: Good question! It really depends. It doesn't work on my phone (which is pretty old and bad), but I've had other people test it and it works ok for them. So it's not something I'm officially supporting (since I can't really test it myself), but I added touch controls so you can play it if it works for you. Connecting a controller should work too if you'd rather have physical buttons.

Q: The game isn't taking up the full window, only part of it, how can I fix that?

A: This seems to be just a problem with some setups, this never happens for me but does happen for some other people. To fix, press F4 (or Back/Share on controller) twice (or just once to keep playing in fullscreen).

Q: The first few notes of some maps are slightly off timing, why is that?

A: Unfortunately that's just a problem I haven't been able to fully fix yet, I'll hopefully fix that (and some inconstancies with the hold notes) at some point. It's usually fine as long as the map has a gap of 2 seconds before the notes begin.

Q: Where is my save file?

A: There's not really an easy way to access it on web, but on Windows it'll be in C:\Users\[your name here]\AppData\Roaming\Godot\app_userdata\Deltarune Lightners Live

There's no "Plus" because that was the name I originally had before release, and I forgot to change it in the settings when first releasing the game. If I changed it now, people would lose their save data, especially on web where they can't just go into the files and copy it over.

Q: Why is there no native Linux version?

A: I wanted to have a Linux version ready to launch at the same time as the Windows build, but unfortunately it had some problems, specifically the metadata for the maps wasn't being read. It's still technically playable, but I'd ideally like to get that fixed before I release it, so I'm delaying the Linux version. Hopefully I can get this fixed at some point, and I'll release it then. If enough people ask I might just upload the broken version, with an in-game message explaining why it's broken, until it's fixed. However, you can use Proton or Wine to play! Note that there may be some bugs with this.

Q: The visuals are buggy, how can I fix it?

A: So apparently there was a buggy Nvidia driver (572.16) that caused this in Godot games. It should be fixed now, so try updating your graphics drivers and that should hopefully fix it!

Q: The downloadable version crashes at start up, what can I do to fix it?

A: Create a new text file inside the folder you extracted the game in, name it however you want, then open it and paste this:

"Deltarune Lightners Live Plus.exe" --rendering-driver opengl3

change the file extension from ".txt" to ".bat".

Now open the ".bat" file, which should run the game

If that still doesn't work, look in the command prompt window that will have also appeared when you ran that ".bat", and see if it outputs any errors when it crashes. Ignore the 3 red extension errors, and 1 yellow icon warning, they're known and shouldn't ever cause it to crash. But let me know if there's other ones, since that could explain the cause so I can fix it.

Q: I have some other problem, what can I do?

A: Sorry about that! I really rushed to get this released before Ch3&4, so I wasn't able to do quite as much bug testing as I would have liked. Let me know about it in the comments and I'll try to help/fix it.

Q: Where can I see more of the alternate music tracks?

A: They're all 8 bit covers made by me, I make them of UTDR and a bunch of other indie games too, here's a playlist of all my Deltarune covers on YouTube :)

I'll be making a bunch of Ch3&4 covers, so consider subscribing if that interests you :)
