Awful. Game saves as you play, so when it crashes at the end of a lvl (which it does often) u keep all the hp/durability dmg & have to do it again. Unresponsive controls, aiming is awful, your char is slower than basic walking/crawling zombies, broken hit boxes, small bag (wants u to spend $ on more slots), horrible translations, text goes by WAY too fast for even a speed reader, ads always give exact same useless reward + have to watch any point bonus ad 2-3 times to get it to actually work.
