Good but needs some improvements with?and zombies – Zombie Gunship Survival Review

I?this game.But needs some improvements with the ? and zombies.First the first gun you have over heats WAY to fast.And difficulty,it says it's easy but then zombies spawn so quickly and like I said before the gun over heats so fast that it's kinda hard.But without the problems love it.????????????
