What is the general difficulty rating of 'FH - Holiday Hentai Connoisseur'? I've attempted it twice and lost rather early.

My first attempt was after a three-week break from fapping. I had no warm-up, focused on a low grip, and played shortly after having a piss. I had to pause at 03:10, 04:39, and 05:36, only to cum at 07:00. I was surprised by how short the in-game breaks are. My second attempt was 12 hours after the first, but was in otherwise identical conditions. I unfortunately had my first pause at 08:13, which was just before the round ended (I couldn't have known). I was losing breath at that point. Despite the pause, I lost at 09:20.

What should I conclude from this? Is it just a hard Fap Hero or am I playing wrong? I think that I either need to train my breathing (how?) or treat pre-game warm-ups as absolutely mandatory.

Also, is it just me or does breathing in seem more important than breathing out? I don't know a better way to phrase that.
