Game I Want to Play Lately!

I haven't unlocked many features yet, but I like this game because the character designs are my type, and everyone is small and cute overall! However, I can't take my eyes off it, so I'm not progressing much ( T T ) The screenshot is my favorite character so far! The rarity is low, but it feels like I can raise it once I unlock features? I'm excited!!((o(´∀｀)o))ﾜｸﾜｸ Simple game description, Tower Defense? Favorite points: You can defeat enemies quite satisfyingly, the characters are cute~!, and the subtly difficult-to-use UI is cute lol
