Title, i like pixel games, just not this artstyle, especially since act 1 is what drew me in

I only recently discovered the game, and enjoyed it quite a bit. From a quick search on Google, it appears that all the claimed "mobile versions" of the game are, in fact, either video playthroughs, scams or trojans. Is there a known way I can play a legitimate version of the game on a mobile Android device?...

Can access my files? Without admin access? That's crazy! (Yes it can't delete anything but it can still read it). Can it like, open the file and see its contents?

Every time I've left and come back, some of my cards have disappeared. I thought at first it was because I left while I was being flown back to my last beacon, but after leaving the game normally, I can confirm my cards are just vanishing. I am down to just a Double gunner, and have lost my orosbot the angler, and the lonely wizard....

Before getting the game, I wanted to check out the demo, but I couldn't find it on the store page, or by searching for it in the store. I am on a Steam Deck if that changes anything.
