Qwinky review
Qwinky is an interactive game with filmed scenes. Its public site describes a browser-based player and offers separate routes for buying credits and taking a membership.
Vertical on phones, widescreen on computers
The site describes vertical streaming for phones and widescreen streaming on computers. It presents both credit packs for individual scenes or quests and memberships for broader access. Its legal notice identifies Interpov SAS and states that performers were adults when the material was made.

A browser game or a headset experience
Dezyred documents a Quest route through PLAY’A and a separate credit-based path for unlocking a game or parts of it. Qwinky advertises a browser player and lets you choose between a credit pack and a membership. If you only have a phone or laptop, the browser format is the first difference to weigh.
Anabel’s take
I'd try a single Qwinky quest on the screen I expect to use most. I'd consider a membership only if I wanted to come back for several quests rather than finish one.
