I think the base game is quite cheap and there are a handfull of dlcs that are really meaningful, which you still don’t need. Also the base game has gotten updates for at least 5 years now so i think it’s fair. And it works good on Linux.

Edit: It’s from 2016, so no wonder there a lot’s of dlcs. The base game has gotten overhauls in the meantime.

That works too but for me it’s mentally simpler to pull another finger than having to press with the same one i use to move over the touchpad.

Mouse heavy games, e.g. Sterallis, you simply move the cursor with the touchpad and click with RT or LT and it works wonderfully

Even if you would be able to track js code like that, the js code can react to it’s own sideeffects. E.g. have 8 Elements and encode the 8-bit Fingerprint as a custom style sheet that adds an animation some of the 8 elements. Then react on the animation events and rebuild the fingerprint. It’s virtually impossible imo. Maybe it can even be formal proven.
