Likely riding on the popularity of the recent Chernobyl series, Escape from Chernobyl is a puzzle game with multiple endings where you take on the role of a scientist based in some secret lab.
From what I can gather (not one I've played), it's an escape room adventure. Full of apparently tough puzzles, that may require a pen and paper to help you solve them. A little warning too, apparently the English translation isn't the best. Amusingly, you can kind of tell from the Steam description mentioning you "visit the skin" of a Scientist, which sounds a little amusingly rude. According to what little the developer says about it, the plot is non-linear with three different endings.
It does have a "Positive" rating on Steam at least, although that's only from around 20 user reviews.
Originally released on July 5th, the developer added official Linux support on July 21st and you can find it available for purchase on Steam.
