Played on Linux with Proton (there's a Linux version of the game, but relies on your browser having flash support and what not). Experienced 2 "major" bugs, which wouldn't let me progress, but by the game's design, it is easy to restart the level with minimal loss of progress. It still makes the experience a bit frustrating as It makes you start to wonder whether you're not getting the puzzles or just having a bug (with that said, most of the puzzles are simple enough this doesn't become a huge issue). Everything else is wonderful, really recommend the experience, even more so at a discounted price.
