I wondered what else the game could run.You can discuss it, and I'll create valuable categories.One of the things that comes to mind is to complete the operation of the two achievements of "Top of the World" and "Airship Man".Although I haven't achieved it yet. But I have this idea.You can post your own categories of ideas.I check messages from time to time, often or at large intervals, depending on whether I'm at school or not.
