Regardless, thank you for playing the game. I welcome all criticism, and at the end of the day I think you're trying to say that the game is too hard, and I understand, I already have plans to lower the difficulty for the full version of the game. Chapter 2 is the only part that has a difficulty spike though, if you can get through it the remaining chapters are going to be much easier, I promise.
I don't consider myself a developer, just a guy who really likes horror hentai and has always wanted to make my own game for fun (I only learned renpy for like 2 months and had no prior background). As for the price, it's only $2 per chapter. I make no profit, the money goes entirely into the game's budget. If there was not enough budget, I would've stopped producing the game at chapter 1.
Regarding blackjack, the issue you described is entirely intentional, it's to build up Binky's character of having twisted humor. She's a clown afterall.
