94 views and 19 downloads in a week, and some actual sales too? Few of my projects even got that kind of attention until this year. You have to keep in mind there's no guarantee. Not even if you market your game aggressively. There's simply no telling what people will like. Or what they'll talk about even if they do like it.

Just to make sure, you are promoting the game outside of Itch, right? You do have a presence elsewhere? Ideally your own site? Itch is the best marketplace... but it's only a marketplace. You can't live in one of those.

Biggest thing I see missing from the online presence of Gunpig is that there is no playable demo. There was a developer I was following that released a game here on Itch a day or two ago -- looked good, nice price point, but there was no demo. People are less likely to buy things if they can't try it first.

I did check the game site out.
Someone had a good point in this thread.
You should have a demo version, cause for me as a student 8 euro is a lot of money and if i use that amount i would like to know what i'm getting.

One tiny suggestion: if you have a link to your game in your post it makes it that much easier and likely for someone here to at least view it. Every little bit helps!

Hello! I'd be really keen to know what other activity you have running in parallel to anything on Itch. How are you leveraging your own studio channels? Where are your cross-promoting? What publications, groups and communities are you introducing your game to? Have you conducted any giveaways? Have you opted into the Itch partner program? Have you blasted out keys via Keymailer? 

As No Time To Play mentions, Itch is just a store here (albeit one with very good community and social integrations). You need to push people here. 

I put together this very top-level marketing support post a while back - perhaps you'll find it helpful. 

If you have specific questions on anything here, I'm always happy to chat and offer specific recommendations :)
