You are playing wrong game mode probably. Quick game is only intended to play quick non-configurable match.

The "multiplayer" mode can be played with one player just fine, just add some CPU team(s).

Yes, the quick battle is very random (including map size), that's on purpose. Maybe the quick battle is a bit TOO random.

This feature was always meant to be a "1-click start" option, but I think one issue is that also that difficulty is randomized. Well, kinda. The first 15 quick battles are forced to be on a lower difficulty and "map complexity". After that, difficulty is fully random.

Maybe a feature can be added to manually restrict the difficulty of the quick game, I'm not sure how it would look like so far …

And I see now it was an usability fail to label the customizable game as "multiplayer". It's meant for multiplayer, sure, but that doesn't mean you can't play alone.

Thank you for the replies.
I must admit I thought a 'quick battle/game' would be just that, a more simplistic landscape that wouldn't fill the whole play arena. I found myself having to scroll out just to find the enemy hogs on screen as they would be so far apart. The vastness in the landscape made getting anywhere or indeed killing the enemy virtually impossible to do in a 'quick' game.

The "quick" in "quick" battle means more like "quick start" than anything else.

But OK, I see now it was kind of a bad idea when the map is too large with the hedgehogs being stretched out too far, indeed that's not good gameplay, either way. I can look into limiting the map size later.

I have added this to the TODO list.
