For those who want to play on a Mac and for whom the game doesn't work (saying the app can't be opened with no further explanation), try this:
- place the application in the Applications folder and rename it BLEED RUNNER (makes the process easier, technically you can rename it however you want and have it wherever you want but do remember to change the following commands accordingly).
- open the Terminal
- run these :
cd /
cd Applications/BLEED\ RUNNER.app/Contents/MacOS
chmod +x BLEED\ RUNNER
- when trying to open it now, you should get a warning saying the app is from an unknown developper, click "Ok". The app should close itself
- open System Settings
- scroll down to Privacy & Security
- you should read ""BLEED RUNNER" was blocked from use because it is not from a identified developer."
- click "Open Anyway"
- another warning shows, this time you can click "Open"
- from now on the game can be opened properly
- enjoy :)
