Contributions are welcome! If you have ideas, improvements, or fixes, feel free to fork the repo and open a pull request.
This project is subject to bugs, fixes, improvements and changes.
This project is open to learn, build, and improve.
You’re free to use it as a reference, a base, or a learning resource.
Because code is not a buried treasure —
code lives when it’s shared.
📚 Learning > hoarding
💡 Sharing > flexing
🚀 Building > gatekeeping
I don’t really believe in the mindset of:
“Don’t touch my code, don't create other engine, don't use my engine's stuffs, bruh...”
Bro…
you’re not going to heaven with your private repository under your arm!
Source code is:
- knowledge
- practice
- mistakes
- evolution
If someone improves something I made, respect 🫡
That’s how this has always worked:
learn from the past to build the future.
Don’t claim others’ work as your own or sell it as original.
Respect the effort, learn from it, and create something better.
To those who share: thank you 💙
To those who hide code out of fear or envy:
relax — progress doesn’t wait.
Happy coding.

- You can change a note's type on the Editor, it comes with five example types:
- Alt Animation: Forces an alt animation to play, useful for songs like Ugh/Stress
- Hey: Forces a "Hey" animation instead of the base Sing animation, if Boyfriend hits this note, Girlfriend will do a "Hey!" too.
- Hurt Notes: If Boyfriend hits this note, he plays a miss animation and loses some health.
- GF Sing: Rather than the character hitting the note and singing, Girlfriend sings instead.
- No Animation: Character just hits the note, no animation plays.
- Working both for Source code modding and Downloaded builds!

- You can change Note colors, Delay and Combo Offset, Controls and Preferences there.
- On Preferences you can toggle Downscroll, Middlescroll, Anti-Aliasing, Framerate, Low Quality, Note Splashes, Flashing Lights, etc.
- When the enemy hits a note, their strum note also glows.
- Lag doesn't impact the camera movement and player icon scaling anymore.
- Some stuff based on Week 7's changes has been put in (Background colors on Freeplay, Note splashes)
- You can reset your Score on Freeplay/Story Mode by pressing Reset button.
- You can listen to a song or adjust Scroll Speed/Damage taken/etc. on Freeplay by pressing Space.
- You can enable "Combo Stacking" in Gameplay Options. This causes the combo sprites to just be one sprite with an animation rather than sprites spawning each note hit.
