The Steam Ocean Fest just started (May 18th) and will run until May 25th! If you want to grab some cozy games surrounding ocean-like themes, then you won’t want to miss out on checking out this list!
For once, you won’t have to worry too much about the dates because all of these sales run until May 25th or June 1st. So, you’ve got time to really sit and think about the games you want to snag.
From this list, I’ve played Collector’s Cove and Loddlenaut and I can’t recommend them enough.
As always, I’ve picked games that have positive review scores and don’t use Gen AI, so you can feel confident in the suggestions!
We do our best not to highlight games that use Generative AI at any level of development or marketing. At the time of posting, these games have not reported or disclosed using Gen AI. Likewise, all articles are written and edited by humans… as evidenced by our occasional errors.
