If you're looking for a growth game, try this one

I started playing Slayer Growth just to try it out casually, but before I knew it, I was constantly checking my character's stats lol. At first, it takes a while to defeat even one monster, but after changing equipment and upgrading skills, it's surprisingly satisfying to see them get defeated much faster than before. The thrill of suddenly clearing a stage that was blocking you after just a slight stat increase is bigger than you'd think lol. And I thought it was just an idle game where you just leave it on, but when you actually play, you find yourself constantly thinking about what equipment to use and which skills to upgrade, so it actually requires a lot of attention. It's also nice to wake up and check the accumulated rewards, and when you compare your gradual growth, you end up thinking, 'I'll just play a little longer and then quit,' but then you end up playing again lol. I can see why people who like this type of game get so hooked.
