I have never heard of "Spindle" until i saw a YT Video where one of the devs i guess talked a bit about it and how they struggle to rise awareness of the release.

I was fully unaware of it!

Yet awareness can be risen on several ways, one is to team up with streamers, then the ususal PR stuff, and ofc the title.
and i honestly would not look for a game named "Spindle" bcs with no other knowledge about the game i would not associate the game with an action adventure but some obscure indie title about an old tale or some obscure game mechanic.

Imho a game with that little PR would need a convincing game title that makes people curious about it and look after the game and my feeling is that was not achieved!

And no, i honestly can not say i will buy it bcs with less discrete money to spend year after year it is no longer feasible to buy a game out of a feeling of sympathie and games like MW5 DLC, EU5, KCD2 DLC, Vagrus DLC etc. are eating up what little gaming budget is left.

Still my hope is it works out for you!
