Doesn't bother me at all, I'm always open to feedback.
In regards to time I understand that it's more or less the most contested mechanic when it comes to Project Red. The 1.8 demo nearly did launch with an easy mode that had the clock starting at 6pm instead of 9 however since I didn't have time to throughly test it I left it out rather than have people potentially have a rough buggy first run.
That being said, there ARE other ways to save beyond resting at camp fires. Ritual Candles can be used at Goddess Statues to save without moving time forward at all. Reaching new chapters will also prompt you if you'd like to save your progress, again with no time cost. And in Chapter 5 you'll have the option to make a permanent free use save point.
The more you play and explore your options in the game the more you'll likely realize that time is barely a factor to consider, especially in this demo. I can tell you for a fact that there's enough time to do every lewd event and save at camp fires a few times while still reaching the end of the demo with time to spare, so try not to worry about it so much. The idea for time is simply to be another type of currency that you can choose to spend as you need it. Do you want an easy way to heal and save? Spend time at a camp fire. Do you want to fast track your relationship with the Goddess Eros or make money quickly? Spend time on lewd requests. Do you want to wash blood off yourself and get some buffs? Spend time on a bath. But all of these things can be done without spending time. Healing items and spells as well as level ups restoring your HP and MP to full. Side Quests can give you money without having you spend in game time. Blood can be washed off by items or having wholesome experiences in the story. That is a long winded way to say that, time is a currency that you are encouraged to spend on whatever you feel you need, when you need it. While failing to reach the end by 6am nets you a unique ending, there is literally no advantage to reaching the end with several in game hours left on the table. So do spend your time.
Thanks for your feedback, and I hope this helps!
