Finally ready for a playtest demo for my grappling-based 3D platformer Koromi

Here is the question: how do I get people to participate now ?

I am a bit worried about the games subreddits shooting me down if I just ask people to join the playtest there. But it's a free (piece of) game after all!

You will find the join button for the playtest on Steam (Koromi) if you feel like helping me with feedback.
