It's a fun game. On my (android) phone it's often very hard to tap on individual customers. Sometimes the ui freezes for 5-10 seconds - in combination I often don't know if I keep missing the small click targets or the ui froze on me.
Apart from that, this is a fresh take on both the story based renpy and the time managing genres, I'm looking forward to the next version. If you need help filling out the missing German phrases, feel free to PM me.
