The game is great and i love it. But the last update with increasing alchemy time was a mistake. If players do not buy battlepass then make a completely different one, this one is boring for players like me who play from the beginning. This is the problem, and not alchemy time. I do farm a lot, top 10 exp almost every week. And I'm out of gold cards now. You should lowered more the time. For example 5 min for blue and 3 for white cards. Finish the map, put another craft, that's how it should be.

I won't lie, I'm addicted and I love it. Some things I hate, The UI isn't resizeable, so despite your choice of method to play, still expect to struggle to see. There is embedded autoaim, so if u love range skills, they still rock, but it gets really annoying. Idk, I'm only a few days in. It just needs more settings, this game has insane frikan potential and I'm in love, it just needs more love on the side of more settings so it's better for pc and mobile. ADJUSTED from 4 to 3 stars

Game has a lot of bugs and technical issues. Developers act as a scammers. They delete your one of your in-game accounts when you try to link steam account to android. They do it without any notification, automatically. You recognize it only if you've read guidelines before or after you have already suffered. In-game support doesn't help you. They just answer "We can't help, f..k you customer!" So any player just loses money if he made any in-game purchase. Scammers! DON'T RECOMMEND!!!!!
