I am a bit late to the party, now at Ep7. But here I have to rant a bit.
Ep1-6 had some great natural progression. Ep7 feels like a disjointed mess and it annoys me to no end.
Ep7 starts with being able to get BJs from Lynn, where she was barely at the point of HJ at the end of 6. No progression scenes, just, bam - lets go.
Its clear the 4 are growing towards eachother, despite the feelings-system being utterly broken (game is complaining about increasing the stats since ep4, despite never giving any option to do so). The amount of crap you now need to pay for increases by a lot, instead it being decreasing. It should be at the point you pay big bucks for the pictures (as is logical), and maybe some small token allowances for small enticements (like before). But nope, only gets worse. Which leads me to the next point.
Economics gets completely wack with the intro of the pay-what-you-want option causing the smallest thing costing 3-4 figures. It is stupid that money is even a factor at all. The game is grindy enough as it is, and it doesn't need artificial crap that detracts from the relationships the game is supposedly building.
Event chains get a soft reset every episode jump (this was a problem before). The amount of times I had to "rebuilt trust" is probably the amount of eps there are. Such a shit design.
Not to mention the hints system being utter shite. With Ep7 supposedly being better in exchange for the skip to be disabled (worst deal in the history of mankind).
Ep7 also introduced that red circle at the top. I suppose that is for arousal? I have no clue, the game hasn't explained anything when it introduces new shit over jumps.
The stats page is also complaining constantly that Lynn needs new clothes and I need to ask her what to buy. Despite never giving the option to ask anything other than in predefined scenes, nor to buy it other than in predefined scenes (which are usually trigged in another shop)
I still like the game for what is is. But holy crap what a bunch of shitty gamedesign decisions. Hopefully it gets better with about 7 eps to go.
