A fun game with an innovative menu, but the enemies were way too fast and you picking up the hammer was hard. I think a mechanic where you can get the hammer back (like in Thor) would make the game better (aka more fun!). Also, it's not exactly original as there are similar games with similar mechanics, because, as far as I think, this is essentially the "You only have One Shot" mechanic. (My game's title also has the words "One Shot" in them, but it's the enemy who has only one shot, to kill you. Fun game, which seems to be heavily inspired by battle royale.
The game *is* fun, but I'm just giving a few suggestions. (I've given a good rating, don't worry)
and this is, by far, the longest review I've ever written.
