Dead Cells

For me the situation is different. When I want to download the APK I'm told that the webpage doesn't exist. I don't know what's going on.

I'm pretty sure that it need a 64bit phone i think you have a 32 bit phone. It says arm64 at the top of the game picture

Yeah it won't support maybe because the game is for arm 64 but your phone is arm 32.

The game was modified like that, you have to pass through that to ether play or exit.

It doesn't has any malware or malicious virus and anti-virus say "can't scan for malware" means it can't scan to look for virus, it doesn't mean that it can't scan because malware blocking them to scan. It just means that it didn't scan for malware. Yeah sometimes it's hard to understand these stuff. If you still have doubts then you can scan that file in https://www.virustotal.com/gui/home/upload , well of course you have to download the file first. Downloading files doesn't do any harm even if they have virus it them. It ether need to be installed or to be executed(which only happens in PC).
