 ## About
 Yet another Geometry Dash modded client! I've been using [GDMegaOverlay](https://github.com/maxnut/GDMegaOverlay) for quite some time, but because it has been archived after the release of 2.2, I decided to make my own modded client. Project is still in early stages, so expect bugs and crashes, but I'm working on it! Be sure to check out the [issues](https://github.com/prevter/gdopenhack/issues) page for known issues and planned features (and feel free to leave your own suggestions).
 
 Main goal of this project is primarily me getting more experience with C++ and game hacking, but I also needed a modded client for myself, sharing it with others in the process as well.
 
 ## Features
+- [x] **Update-proof hacks!** (most of them should work even after the game updates)
 - [x] Customizable menu with animations
 - [x] Basic hacks (speedhack, noclip, etc.)
+- [x] Hack search
 
 Planned:
 - [ ] Keybinds
-- [ ] Hack search
 - [ ] Auto-updater
 - [ ] ... and more!
