Idle shadow feels like an average game. Everything in this game can be found in other idle mobile games but better. I dislike the vertical play style the game has. The worst part is that they have all the upgrades for your character shown underneath the battle scene. It feels like they just tried to squish it in there and be lazy instead of making a new menu system for it to show up and cover the screen. When I am upgrading my character and assigning skills points, I am not looking at the battles, so it seems pointless for them to do this.
The variety of different skills you can acquire, and use is nice. However, the animations that show up when you use a skill are very subtle and not visually appealing. The game has a cash shop, but you don't need to spend money to enjoy the game. I think it can be fun for maybe a few days if you play it casually. The game just lacks anything that keeps you interested and wanting to play more. I don't recommend this game only because there are way better idle mobile games to play.
