Also, for the record. If you want a fast playthrough, just use save/load. It resets most of the daily/weekly events. That way you don't need to do 3+ weeks of skipping to wednesday for the bike race for instance. Just do it once, go to the room, save, load, go back to the event and do it again. You can usually get out of debt, be at 5 star Anna and finish the celeste storyline in under 25 days passed.
Please dont do this. This can, and has, broken the game and caused save collisions before, doing it normally during gameplay or once or twice is ok, but don't abuse it.
As for a skip button, there already is a fast skip dialog button on the top menu. Ofc is not going to be like the "renpy ctrl" that skips over everything at the speed of light, this is a unity game and doing that can break most interactions.
Having rigurously tested this method for probably like 40-50 hours of playtime at this point I haven't encountered a bug with it specifically once. (Can't really speak for edge cases etc. though. 🤷♂️)
And that's me talking as a professional tester with over 15y experience.
Most of the issues there were with doing the same thing over and over were you encountering other bugs in locations more often. Most of which have been fixed at this point. I could also just be avoiding the bugs unconsciously at this point tbh. Not ruling that out.
But sure, it's not intended and use at your own risk.
It's just too damn convenient to do 3x bike race in the same day, do all 3 Tristans and get heavenly husband, do 3x depression talk in the same day and not have to wait up to 10 days for her to be drinking again etc. The 'do this on only monday' stuff reaaaaally slows you down, especially if it randomly rains now (or snows) and you just lose another week of progress on it. Nobody really likes dealing with bloat. It's fine for the first playthrough. Or the first few. But not when it's the 6th time playing through 😅 (or the 20th 😛)
I guarantee you there are replication workflows using the room save method, which results in quests not triggering correctly and CGs not loading.
It will never get resolved though because it is not an intended play style.
It is not recommended at all if you want to see everything the game has to offer. But as you mention you can do so at your own risk.
It needs to be highlighted though, if you do this the developer or mods are not going to assist you in the mess you create 😅
No plans for a NG+ way of playing, that might change, but none as of now. Although the one thing that might happen is keep increasing simplicity of play. For example, the new trait system will allow for the player to pic a specific trait from the get go, so in cases like Amelia, you wont need to do all the Phoenix trainings for the trait.
Cool, anything that makes alternative playthroughs simpler is a bonus so happy with that. Thank you.
Context - The current grind is good for a first time playthrough imo, but if you want to see other outcomes in a second to 50th playthrough, I can understand the eyeroll at the multiple tasks and waiting days. For reference games like Love & Sex: Second Base by Andrealphus handles new game plus really well with picking extra traits and money in your pocket at the start.
