CAT Interstellar, a rather short sci-fi "walking sim" that I quite enjoyed after playing it back in 2017 has now gone 100% free to grab.
Speaking about it going free on Steam, the developer noted that they never actually expected it to make any profit. However, they did manage to ship around 100k units across Steam, Humble Bundle and the Playstation Store although most were from sales and bundles.
What they did with that money is quite sweet though. Grossing around $8k a year across four years, the majority of it went to fostering animals and donating to their "local humane society". They never really promoted that until now when it's free, as they thought it would have been a "sleazy sales tactic".
If you've got around an hour free and nothing to do, taking a look at CAT Interstellar might save you from some boredom and leave you with many unanswered questions as it did for me. They also updated it recently to add in a few small fixes.
Also mentioned is that they're still developing CAT Interstellar 2, although progress on it has been slow since they have a family and full-time work. It will be interesting to see what they do with a sequel though!
