ZOMBIE WARFARE: Shooting Game

Game was ok nothing to brag about but I put some money in to support game a while back been playing bout 6 months then the other day game decided to restart itself and I’ve lost all my progress I’ve earned and spent money on,and yes I was backed up by fb. Would I recommend your game to anyone ?what do you think. Ok update the problem was on there end it was fixed and all my progress was restored ,thank you very much

First off, this game has great potential. Nice aiming mechanics and movement. Decent weapons loadout and character classes, albeit rather expensive. Stability issues: prior to the recent update I could play several rounds without the game crashing. After the update I’m lucky if I get two rounds in before the game crashes. Also, you loose the energy (levels require a certain amount of energy in order to play) used each time the game crashes, making it even more frustrating. Finally, level 9-5 will not load at all...not even once. The campaign goes up to 30, and weapons are unlocked via campaign progression. So now I’m stuck grinding the lower levels, at least when the game doesn’t crash. If the devs can fix the stability issues this game would be awesome and get a 5 star review. I already spent too much real $$$ to just give up on it, but the crashing is making the game unplayable.
