I have such message "The app isn't compatible" on my Android 14, it's usually skippable message.
If you click Ok, you can play... is it working like that for you?
Also we're working on the hotfix for latest Android now
most games I've played still allow game to run after clicking the 'ok' button but for some reason this game fully closes itself off completely and then when try reloading the game up it just instant closes again without the message. I do also use JoiPlay and downloaded the windows version hoping that will work but it's not compatible with joiplay it says shamefully. I'm not after a refund as end of the month I should have my new laptop and quality of your games look rather interesting, I'm just eager to play them for myself.

Check out the new testing build "Wonder Slave 0.6.5 - Android 14 (Hotfix Test) - Episode 1-6", it has skippable "The app isn't compatible" message, but working on my S22 Ultra (Android 14)
>>> READ MORE IN DEVLOG
the game installed and gotten past that message. If had the previous file you must uninstall that one as it doesn't just allow you to update but that version works greats for the android with skippable message. Once tried the game out properly I will leave you a review on the game too. Thanks for the quick fix. Will this game be receiving further updates and things or is this game fully completed now?
I glad that it helps ;), if you find some bugs, just write me in Our Discord
"Will this game be receiving further updates and things or is this game fully completed now?"
Next updates it's mostly like DLC, the main loop is finished, we're just going to add more hentai content for additional scenes. 
There're latest Wonder Slave testing builds on our website, like WST 0.7.
It's avaliable for closed testing for all SubscribeStar & Patreon backers
And we've a pre-rendered content for the next 0.8-0.9 releases, there're some posters on the Wonder Slave game website.
Becouse of the war in Ukraine we lost access to our main server with all code & rendering hardware, so it's pretty hard to say what time we"ll go forward with next Wonder Slave development, I have a hope to do it before New Year, will see.
