Thank you so much for your comment :D
It's true that I can't help but put in a lot of content and polish, even during the trijam which should push you to get to the point!
I'm very proud of this mini map, I must admit. The non-displayed asteroids were indeed intended to prevent players from driving only with the map open. And in any case, when I did display them on the map, it certainly looked very nice, but it also slowed down the game a lot. There are 1000 asteroids in all, and 600 of them are already displayed! Anyway, I'm glad you're driving carefully - we wouldn't want an accident to happen!
