This is only tested on Windows 10, but Unity is pretty good about cross-platform so it probably works on Mac, too.
- Download this repo. It might take a while because there are like 10,000 tile files because unity stores every tile as a separate file because it's a silly engine.
- (Windows). Install Unity 2017.4.31f1 (64-bit). . (Mac). Install Unity 2017.4.40f1, as there seems to be an OGG importing bug n 2017.4.31f1 on Mac.
- Optionally, purchase and download ReWired if you want to re-integrate controller support
- That's it. Wow! Actually you have to wait for unity to import all these files the first time you open the project, which takes a long time.
- After waiting for a long time, if you'd like to just play the game, open the "Title" scene and then enter Play Mode.
- Note that this version of the game uses a different save file location, although it'll still be under Analgesic Productions LLC
- This is only necessary if you want to export your own versions, mods, etc.
- Open Build Settings (Ctrl Shift B), ensure all 62 scenes are there and checked.
- Change the Player Settings if you want to.
- Hit Build! This will take a while due to shader compilation.
