I corrected a typo concerning the minesweeper: I wrote 58 instead of 57 for a variable, the indications concerning a mole in the middle were then wrong, this mole didn't always appear (it's random) so it's possible that you didn't notice anything. I checked all the other variables, it looks ok so there shouldn't be any other problems.

As for the optimization, I have to keep working on it so that the android version doesn't crash, other renpy games seem to have this problem.

EDIT : The game lags during the fight because of the variable to free up memory, so I'll release another update to fix this in a few hours.
