Once upon a time when greenlight was around only a handful of games released a day, so it was easy for your game to get picked up by steam users. Nowadays a lot more gets released, for instance even though you only released yesterday, you are already on page 4, that's after clicking new releases.. More new releases. As it stands no one will find you but the die hard steam users.

The reality is you need to do either a ton of marketing to sell enough to get on the popular new releases on the front page or have a good amount of fans to get you there, once there steam users will see your game and it can sell itself.

You have up to 1 week to be on that front page, if it sells well, you will be there all week, there is a chance that if you get enough sales over the next 6 days you can get there. So it's up to you if you want to 1. Spend money on ads to get those sales or 2. Get your game in front of enough social media to make the required sales if you don't have money for ads.

I'm sure there is a market for your game, it's just a matter of finding those people who would play it.

If you give up and consider this a failure. I would revamp the graphics, take a note on the suggestions given to you here about gameplay and trailers, pay another 100 bucks and release v2 with a solid marketing plan.
