Thanks for playing the game! We're trying to make the CLICKing and seQuence as mundane as possible because, well, the point is nobody actUally know what the button does. It mIght be pointless. But you keep clicking anyway. Because That's resilience (or is it?).
And as on how to reach the endings...I've left breadcrumbs on this comment :) There's 2 endings and 1 secret ending to unlock :))
