Hmm, had a similar issue but only with this game, and on pc (so not an issue with your phone I'm guessing). On PC at the bottom there was always an additional option "reload" which always helped and allowed me to continue. Still curious, if you figure it out, lemme know what was the issue..
BTW (Personal message), if you really want to start in this business as you mention below, I might be interested to cooperate in terms of writing (no programming or rendering, not my strong suit), dialogues, characters etc. I've had my share of experiences with ladies and I'm told I'm empathetic and do have a way with words (by women and ex-girlfriends naturally), so working or helping with that I would be up for. Sounds like fun to me..
Would have DMed you, but doesn't seem to be a way to do that here (or I'm just too f*king old for this s*it). If you are genuinely interested to give it a shot, and need/want someone for this, gimme some contact (no social media please, email or discord works). Either way, good luck, hope you will create another AVN I can praise here :)
