Hey, thank you for the reply.
Of course everything I said is just to consider if it's a good idea and worth your time adding to the game, for you to decide. Or future games. There are so many fetishes out there, last thing you wanna do is burn out, but if you will add a pdf, I think it sounds like a good and easy, fast idea. If anything, I just hope when the nude skin will be available, she will be actually very nude, like barefoot :D
Another thing would be nice to add in the pdf is numerical indication how much upgrades affect you. For example, it's obvious from gameplay that bomb upgrades give up +5 maximum capacity, but max health doesn't give you the exact numbers how much more life you get, and it's hard to judge by testing from being hit. So if original health is 100% or 100, then something like "+20%" or whatever the actual numbers are would be neat to see in the pdf or tooltip per upgrade. Just an idea for better clarification.
Cheers!
