I am looking for a casual puzzle / shoot'em up PVE side game where you require a thinking / planning to solve each specific stage while blowing up tons of enemy in between with a lot of character to build.

I would prefer to login around 1 hour a day, progress at my own pace and still be decent at the game.

Something similar to Arknights / Azurlane. Preferably with some element of resource management but not required. I don't mind buying some value packs (<30USD / month)

Game I enjoy and currently playing:

Epic 7, Touhou Lostword

Game I enjoyed but quit already:

Counter Side, Arknights, Granblue Fantasy, KanColle, Azurlane, Seven Knights

Game I tried but dislike:

Girl Frontline, FGO, Dragalia Lost, Fire Emblem Heroes, Lost Eden, Genshen Impact, Honkai Impact, Langrisser

Thank you in advance !
