We will make more challenging games; this one is for everyone that knows the meme can have some fun and see the end of it, even if they are not skilled players or players at all. The next games will be more oriented to regular gamers.
I don’t mind that most of the game is a rip-off from fallout; I still like it and definitely would play it. But I'm not crazy about the main character; I rather play as a human than something that doesn’t seem to belong. I’m not sure if that supposed to be your attempt to make it original, but I don’t think is the best idea. Other than that, you are making a great work.
I did an extensive testing; I finish it twice, on a laptop and a PC, before and after publishing. I did not ask for a 5, I said a generous score, meaning that if you feel that it deserves a 2, you could give a 3, only if you feel like it. It’s a hard game indeed and maybe gets a little frustrating on the final levels, but is not impossible, I personally make sure of that.
Blackjack payment rates - Actually, you did get $1500. The message field only shows how much you win/lose of your original bet. Sorry, if this is kind of confusing.
Double and split - You do have those choices. They are not available if you don't have enough money to double the wager, though.
Multiple decks - I’m working on it.
Game play sucks - Working on it.
