I really like these types of games. Playing this game reminded me of this maplestory archer game I used to play as a kid: https://ayumilovemaple.wordpress.com/maplestory-flash-game-download/#HunterStory
March of the Slime King feels off to me compared to this maplestory flash game though. I don't like how much time you have to wait between shots, and I find it very hard to predict where shots will land in this game.
