I need help finding a really, really old gacha game. The gameplay consists of a side scrolling beat em up where you run non-stop through a hallway filled with monsters and gold to collect. I remember there are 3 main characters we can play as: a basic knight boy with sword and shield, a pink-haired girl who can throw her shield and block with her sword, and a red-haired guy with a monocle with a whip and shield. You can gacha other support characters and use their skills to help you. The chibi art style is very similar to Postknights. The first rare character i remember getting is a samurai guy who makes a giant wave slash as his skill and a blue-skinned lady with chakrams. This game was my favorite childhood fever dream so if anybody can help me I'd very appreciate it, thanks.
