Although it's a bit slow at the start, this game gets very wild and fun with just a couple hours in game. I doubled all my earnings for the first 20 levels or so by watching ads (not everyone's favorite thing, but whatever) and found myself pretty strong. The different weapons are what make the game really pop though (along with the Projectiles upgrade 😍). Currently I've obtained a giant epic flaming greatsword that fires about twice a second and shoots 4 projectiles at once. It's truly epic.

First Idle game I'm actually hooked on. Good mix of constant interaction, and idling. One gripe. The Mob invincibility frames as they spawn. Why? It needlessly adds time to the game. I don't want to shoot them off screen. But when on screen I want them damaged immediately. The invisibility frames just extend the time it takes to proceed to the next day.

Been playing this game constantly since I downloaded it. No annoying pop-up ads, simple and addicting gameplay, very very reasonable progression, no terrible time locks (energy and such in other mobile games). Definitely an amazing time killer. Devs are gracious enough to allow the standard 2x loot for watching a short ad. Purchases are not necessary whatsoever to obtain better equipment and allies, but they can speed up the process. Definitely a keeper.
