# Between Ridges -- the Windows installer.
#
# Run from PowerShell with
#
#     irm https://daily.dataswizzles.com/install.ps1 | iex
#
# Downloads the current playtest build, unpacks it into Games\BetweenRidges in your user folder,
# puts a shortcut in the Start Menu and on the Desktop, and launches the game. Run it again any
# time to update; your saves and settings live elsewhere (AppData) and are never touched.
#
# Why a script and not a download link: Windows shows "Windows protected your PC" for any
# unsigned program that a *browser* downloaded. This fetches the build with curl instead, which
# leaves no such mark, so the game opens with no warning at all. The build is exactly the same
# file as the zip at https://daily.dataswizzles.com/windows.
#
# Everything below runs inside one script block so nothing it sets leaks into your session.
