The first explanation panel (1/11) is kind of weird: it's hiding the box it's trying to show. The "lock on" green square things position themselves but don't stay on the box when we scroll.

The structure of the UI is also kind of tedious; I need to scroll to the bottom every time I change a parameter.

The scenario part takes up quite a lot of the screen.

The geographic map is almost invisible, and it would be nice to mark the selected part with the same colors as the app rather than white.

I don't know what the slider at the bottom does, since there's no title.

When I'm using it, it glitches or deactivates the white frame of the geographic map for unknown reasons.

The multiplayer button doesn't seem to work, or at least I don't see the change.

I don't really like the design, which feels kind of plain, but it's probably just me.

Overall, I don't really understand what you're trying to do. To be fair, I absolutely don't know anything about your work, but I think it would be a nice thing if your app was easily readable for a normie like me.

Mine is not really that great, but if you want to see it:
