as far as mobile p2w autobattler junk, there's not much new here, it has all the hallmark ♥♥♥♥♥♥♥♥ surrounding these titles:

♥♥♥♥♥♥♥♥ screenshots.
♥♥♥♥♥♥♥♥ trailers.
♥♥♥♥♥♥♥♥ description.
♥♥♥♥♥♥♥♥ p2w.

but unless you're familiar with these practices, you wouldn't know from the storepage alone, in fact you wouldn't even know it's an autobattler - because nowhere on the store page does it mention that and none of the screenshots or trailers shows actual gameplay.

so by now you're probably thinking "okay so these games are a dime a dozen, why does this deserve a seperate thread" - well according to this forum thread https://steamhost.cn/steamcommunity_com/app/3111890/discussions/0/4766584846444510556/, the game might actually be stolen(or it's the same game released under a different name) - the topic starter is also correct there's zero information of "Gates of Midgad" and to see actual "gameplay" you need to search for "Flames of Valhalla".

here's some actual gameplay https://www.youtube.com/watch?v=5xct4XpC-vc&ab_channel=Android%2CiOS%2CPCGameplay-PROAPK

the google play trailer is slightly more honest(as it seems to show some "gameplay")
the Gates of midgad is the same but with the gameplay cut out.

also super dodgy "facebook gift" advertised on the store page, I wouldn't suggest you actually engage with these scammers on facebook. not entirely sure where Valve stands on something like that, but it seems like it shouldn't be a thing on steam.

also being from Denmark, I take personal offense to their depiction of norse mythology, it has absolutely zero ♥♥♥♥ all to do with norse mythology, they couldn't even spell "midgard"/"midgaard" correctly for heavens sake! so go report the game.

ps. also positive reviews are sus.
