You need to extract the archive and inside you'll find a "HumanCargo.sh" file. You should be able to double-click that (or run it from a command line).
On PC, you'd hover over the save game and hit the delete key on your keyboard. There's not a convenient way to do that on Android, unfortunately without a physical keyboard.
I don't like when they're too hard either. SO, the mini-games have a difficulty level (Easy/Hard/Normal), and you're also able to skip them if you don't want to do them!
That one is found if you're curious about Zed's anatomy.
(SPOILERS)

That's a new conversation I added and I forgot to account for old save games. Hitting Ignore will let the game continue and I'll make a patch to fix it before the next release.
You have to have oral sex earlier with Razix (I believe in Chapter 5), and then have sex with him in Chapter 6. That will get you #16 in Chapter 10. If you did this and also told Razix you loved him earlier, then you'll have the option to top him and that will get you #15.
In Chapter 4 after you eat the sticky meal, you go to the locker room to clean up. If you haven't been playing the game shy, you're given the opportunity to "Take a Peek". If you do that, you'll become curious and when you explore the ship you can look at the anatomy book in the med bay.
To get that one, you have to peek at Zed in the locker room, which will make you curious. The when you explore the ship later, go to the med bay and you’ll find Doc’s anatomy book.
Yup, this is correct. Choose the Kol route, but avoid any kind of romantic contact with him. When Nasir confronts you in the galley, you'll get three choices.
