As of the recent update the Linux build of AirLoveEngine no longer downloads, I will be immediately fixing this bug soon. I am currently in the process of moving and do not have access to my main PC as of this time, please be patient. in the meantime, if you are playing AirLoveEngine on Linux/Steam Deck, you can run it through proton experimental, and it should work just fine. As soon as I have access to my PC I will also begin fixing other bugs that were brought up to me about controller support. Thank you for reading.
