I make a game about trams

Noone cares?

Seems like a very specific niche. But I guess there are dozens of train titles, so there must be a demographic for this.

You provide steam keys (maybe, because you can't even guarantee it getting greenlit) or torrent link.. Uhu.
People would want to buy from a decent shop, else they will say why would i pay to get a torrent link, when i could just torrent it for free?
Even the way you make a joke around it with joke... not really... doesn't give confidence.

Not my kind of thing, looks interesting at its base level from the video I saw, however as someone with little to no interest in trains or trams or whatever I don't see the fun in just building random train tracks. I want to have specific places to build to connect to, so for example the minimalist background doesn't appeal to me as a casual gamer not specifically interested in transport games. I do actually like the minimalist art style but it'd be cool to see maybe minimalist "buildings" or road layouts or just simple places to go or have to build around or places to get to. I don't understand the fun of arbitrary train tracks going from a dot i made to another dot I made, that's not to say people with more interest in the subject matter wouldn't find that interesting. Just my two cents on what might attract more attention, but it depends how much you want to change your niche market. As for the indiegogo page, I'm not really a good one to give advice on that, I know what games I like and don't like, I'm not so good on how you should market them.
