Yeah, the new update makes this game slow complicated and sucks out the fun. I'll come back in a few weeks to see if it's been fixed. Till then i'm revising my vote down to one star.
Some kind of checkpoint system may be a good idea. Once I have the 3rd ship I spend the first half of each run just waiting for something to appear as missiles/torpedos have killed them before they enter the screen.
This is a good game worthy of 4/5 easy. I find I canno't give this rating due to how needy the game is with all the like/follow crap and the premium content add.
Flying zombies either need to take damage while flying or bullets need to pass theough them. As it is now they act as sheilds for all the zombies behind while taking no damage.
