Can't install (v12a on Android 10).
It starts the install then ehen the progress bar is full it just says "app not installed". Installation from unknown sources is active.
How would I know? Why would it need that much RAM? I've installed larger packages.
I tried with a fresh download, now I get "error parsing package" instead :(
UPDATE: seems you were right about RAM. I even had to close the itch.io webpage. Then with nothing running but Firefox downloads list, it finally installed! About 2.5 GB of RAM should have been available (guess), rest is used by Android itself and FF.
