Not showing off coding super powers today, but level design and marketing - and today got confirmation something is working.
Our game level 8 was too hard, but instead of changing it I replaced level 7 with a tutorial.
The problem players had was "can I do this movement?", where the answer is NO. With a bit of tutorializing, and a bit clearer UI (red areas linger on longer) it still wasn't obvious, but it is clearer than before.
I've been contacting YouTubers to cover the game for several weeks now and I'm looking at about 11 % "success rate". I must say that YouTube mostly showing me content creators with over 100 K subscribers is really hurting me as there's no way I can reach those with this game (and lack of previous success stories).
But with the latest YT contact I got confirmation that the level is passable, and also that demo playtime is around 30 minutes (which is about what I was aiming for) https://www.youtube.com/watch?v=DsHc7umek9w
Of course, game is 100 % coded by me, assets by better half. Only external stuff is the music, sound effects (excluding ghost sounds, that's me speaking to the mic) and font.
