You can get a preview here.
With JaDownloader enabled, past this in your browser URL bar jaloader://install/Jalopy-Mods/PaperPlease.
For using the mod, you need to have JaLoader installed.
Then, you just have to download the mod from the Releases, and you can drag & drop both DLL and the folder, in the Mods folder in your Jalopy folder (the one that you can choose while setuping Jaloader).
If you have any questions, you can contact me on Discord: @meblikea, or join Minskworks Discord server. Also, I'm open to feature suggestion/ mod suggestion =)
