Play it before it’s finished
The beta
At some point soon there will be a build of this on TestFlight, and this is where the link will be.
Free, rough, and not a demo of a finished game. It is the build handed to people who did not make it, to find out whether the central claim holds up: that a marble going over the edge of a mountain is funny rather than annoying.
BETA — NOT YET
There is no link yet
The build is close, not up. When it is, this box becomes a TestFlight button and nothing else on the page changes — so if you have read this far, you already know where to look.
No date, because a date would be a guess and you would hold me to it.
