I can't multi-task. I can't do anything if I am listening to a podcast or I miss whatever they are saying. Not sure if I can play Picrsoss with something like that, but it can be worth a try.
I am still on 10x10. Since S4, I switched how I play these. Instead of completing Picross, then Mega Picross and so on, I do one page of each (except colour, tackle that in the end), and do Clip Picross as soon as they are unlocked. Makes it more fun for me that way.
That rewind features sounds nice. Does it invalidate your star / medal rating? Cause I play with all helping features disabled to get that star 😀
Yeah, I like to read, and it sounds like an interesting concept. Also no branches means no need to replay 😀
Both Gal Guardian and Bo are on my wishlist. I am more interested in Bo than Gal Guardians though, so will vote for that. On the other hand, if I had to pick for myself, I mostly play from older to new, I would go for Gal Guardians first.
As for VN, unless I am confusing it with some other, I have heard you mention Witch on the Holy Night before a few times, so I would say it's about time you play that, but going by the pictures my recommendation will be Silver Case 2425.
I hope that was enough to confuse you a little bit more.
