Hello.

Is it mandatory to use the poki version of the game (https:/​/​poki.​com/​en/​g/​stickman-hook as mentioned in the rules) or can we use another version?

The problem is that the poki version got a skin update like the one seen for the android app, so there's a popup at the end of each level indicating the unclok percentage of a new skin.

Thanks for your answer.

It is not mandatory to use poki. In fact, I use the Chrome Extension (that could be hard to find). The Extension didn't get updated.
