I'm so sorry to hear that you're crashing! Unfortunately, I don't think I can actually fix this, as you're crashing during the normal story parts of the game, which are the least resource intensive parts, then I think your computer doesn't have the requirements to run it perfectly :( Can you do me a favour and hit F2 while you play the game and let me know your FPS? It should run at 50-60 FPS, but anything lower and it means the game is too taxing on your computer.
If you hold down your mouse button/spacebar, you can speed up the scenes until you come across the next choice. I will keep my eyes open about any possible 'skip' functions that people may release, but at the moment, this will not be an option.
I will add a load button to the game in the next beta though. Currently you can only load when you first start up the game, as it's mostly meant to be played as having one single save file. Tailor Tales is not like most VNs where you save right before a choice, as this might screw you over or put you on a different path. I wanted to avoid this kind of 'gameplay', so the two different endings are really easily achieved - pick the first choice for the first ending, and the second choice for the second ending. Choices only change a bit of dialogue, sometimes a little bit more, but they don't divert the route into a different path unless the ending is near.
During story mode, you're locked out of the menu, but I will keep an eye out like I said before, for any scripts that allow me to add these options (I would prefer a log, myself).
As for Neil and the fiancee plan, it's definitely something that will come into play the next few chapters. Probably not in the more traditional way of creating misunderstandings and being forced to act all in love etc. but it's definitely the third and final act of Neil's route.
I'll think about adding his original hair colour back, I wasn't planning on it though. But hey, his second ending hasn't been written yet, I might be able to squeeze it in.
Hopefully you'll change your mind about Dimitri, as the MC thinks about it the same way you do. If you're into sweet romances, then Dimitri is your guy. His ending is cavity inducing sweet.
And well, about Sam ... I don't know what you're thinking ;) one of the key themes to each and every guy's route is finding out who they really are though. It's a pretty central plot to Aiden, Caine, James and Sam. Dimitri's was revealed in the first chapter, Neil's was chapter 12. And Sam, I guess you'll have to find out haha.
Thank for your feedback!
