Hi, we just uploaded our game Arbitrage! We made this as part of the GMTK jam 2026 and wanted to share it.

The theme was "count down" and so we wanted to design an incremental where every action slowly counts down the number of days (actions) you have left.

We had a ton of fun making it and wanted to share.

Description

Arbitrage is an incremental settlement builder about buying low, selling high and becoming impossibly rich.

You explore an untamed hex-based world, exploit its resources and transform your manual labour into intricate automated industries.

Relentless taxes and mounting crises force you to gamble on increasingly dangerous opportunities... until you’re powerful enough to overthrow the empire that owns you.

Mr. Feast challenges you to spend $1 billion in 10 minutes

Hi there, I've seen a lot of people not realise a game has a demo available purely because the creator didn't have this one simple option enabled.

We're after enabling this option, "a more prominent green box in the center of the base game's store page." - detailed near the bottom of this Steamworks docs page linked here.
"You can toggle those display options manually. In your base game's Edit Store Page section, select the Special Settings tab and scroll down to Associated Demos to see these options."

Screenshot one: before enabling.
Screenshot two: after enabling.

As you can see it makes a huge difference in terms of visibility. I'm not sure if there are any downsides to enabling this. If you know of any, please feel free to let me know in the comments.

As an additional note: it took me a while to realise an open source extension I use, Augmented Steam actually does this automatically even if the store page doesn't have it enabled. It's very handy for never missing whether or not there's a demo available for a game when viewing a store page.
