The last sentence got cut for some reason ^^ Here it is :

“If anyone is interested in collaborating, please let me know !”

Ah, I found a source of art and gameplay footage. It's copied from https://steamcommunity.com/app/356650.

I'm irrationally angry at the post and its author.

Hello all, I've been working with a team to create VoxStory a new voxel based way to play TTRPGs over the past few years and have finally gotten to the point of having a playable demo, if you get chance we would all love some feedback!

instead of asking random people on the forum, it might be better to post an AD on hobby project classifieds  or other game dev community sites like indiedb and readdit. 

Without judging the contents of the game, it seems you are asking for quite a lot. People have to register, play the game, maintain a list of remarks and then report it all back to you.

Basically you are asking people to do work without offering anything in return.
