You didn't oversell chapter 6. That party is a thing of beauty. You really nailed the big party feeling. I also really liked how the different sections have completely different vibes. Also obviously a ton of character progression that felt very natural. Yeah, I really enjoyed that one.
Am I right to assume you're planning two ways to follow the Grace route? So far I only tried to annoy the living fuck out of her, expecting exactly what happened at the end of chaper 6. (Trying not to spoil for others here.) If there's a non-antagonistic way, it's probably more of a slow burn, I guess.
In my last playthrough I took a more conscious look at the minigames. I mostly like them. Exception is the treadmill minigame. That one stinks, sorry. Also you need to progress towards it with the mouse button and then switch to the keyboard when the timer starts. Meh.
Block Breaker would benefit from a different background while actually playing. Something more uniform with more contrast against the ball. As it is I sometimes lose focus of the ball, especially with the portal blocks. Feels a little unfair.
The Beer Pong game feels harder than probably intended. I have a really fast computer, but it seems like there's still some input lag that makes it harder. I guess it's not exactly what Ren'Py was made for. Making the "hit boxes" just a smidge bigger might already alleviate it and make it feel more skill based.
I really like the general idea and implementation of the Blackjack game. Something about the end condition seems rather weird, though. I must have played it dozens of times now, because I wanted to see how specific endings play out like mc wins or Molly wins etc. Almost every time when I expect the game to end, there's a tie and two or three characters roll back. That happens about ten times in a row until the game ends which makes it somewhat annoying. Also in the end it feels almost random who wins.
The tests have two broken/misleading questions:
1st test 12th question "Who invented the steam engine?" There's no single person who invented the steam engine and when James Watt came around it was already well invented.
3rd (?) test 1st question "What is the most spoken language in the world?" Asked like that the correct answer is English. To match the current answer the question would have to be "What language has the most native speakers?"
Thanks a lot, really glad Chapter 6 landed the way I hoped, that party was a lot of work so it's nice to hear it paid off.
On the minigames, yeah they're not perfect, I'll go back over the older ones at some point to improve them.
For Beer Pong specifically, the hitboxes are actually already enlarged. The real issue is that Ren'Py's tick system is tied to FPS, so if I use a timer other than Ren'Py's own, it starts lagging instead. I've set different speeds for 30 and 60 FPS to compensate, but I'd need to do that for every possible screen/refresh rate combination, which isn't really feasible right now. Still looking for a better solution, but I don't have one yet.
For Blackjack, it's just a pretty random game by nature, some rounds are quick, some drag on for a while, that's mostly luck of the draw rather than a bug. Early on I hadn't added the mechanic where you can come back in with a blackjack, and rounds ended up being way too quick, so this is actually an improvement over that.
You're right about the tests too, I'll fix the wording on those questions.
To answer your question without spoiling anything, yes, there will be two ways to go with Grace.
