Well I suppose that it depends how you look at it:
When we learned about the team, with brainstorm for more than an hour with the team and get some idea as "A stealth game where you can't hide", etc.
One of my proposition was: "A driving game whithout steering and without direct gas/break mechanic". At this point, I was thinking about a spaceship with a tractor beam.
But as some point, MaxiPoki made a joke about the fact that I wanted, before the jam, to make a game based around trains (because "I like trains") and our two artist also liked this idea. We thought it would also be a good way to explain the reason why you can't steer and we would still be using this original mechanics of the "tractor beam" turned into a grappling hook, then a magnetic grappling hook.
Sadly, due to time lack, we didn't add other competitor or the feature that would allow you to change tracks to overtake them and/or replenish gold. So it feel less like a racing game in this state. But still, I think it respect the theme and the genre is "Driving/racing game", I do'nt think you can say that there's a "minecart" genre. Well I never play to this kind of game and for me game genres are not as much accurate but more like that : https://en.wikipedia.org/wiki/List_of_video_game_genres
But I can see your point ^^
Thanks a lot for playing it and for your feedback :)
