These are the C# scripts from the Unity version of HyperBowl, not including any third-party or Unity-provided scripts, and also not the original assets licensed from Hyper Entertainment.
The HyperBowl-specific stuff is mostly under the Hyper directory. The other scripts are general-purpose (even the bowling scripts are used for other bowling games), so not all of them were used for HyperBowl.
All of the builds I had on itch.io are now here in Releases. Feel free to download but please don't redistribute. Link here instead or to the HyperBowl website, which also links to the App Store and Steam builds.
