The working out how to play was always a risk going this minimal, definitely could be better with some more suggestive UI. And the lack of an end screen (returning to menu) was a time constraint choice, don’t expect anyone to play it that far through.
As for the automatic playing of it, yeah so it turns out I uploaded a test version that plays itself (was testing game duration) so that’s my bad :D
I’ve uploaded the correct version to fix this.
