I fought the enemies at the gates of the clock tower and it said "Thank you for playing" and that is the end. How do I enter the clock tower? Is it by doing all the side quests? And where do I spend the Minutes currency to buy tea flavours?

I'm on an AZERTY Keyboard, and the use of WASD for the movement is painfull Try to use ZQSD on you QWERTY Keyboard to see that.

when I try to apply the change and exit the menu they don't stick and the discard changes screen doesn't go away until I reset the game
