I really like the gameplay. No bugs I found. It's just that it doesn't give a good tutorial on what are the controls for bombs and how to use medkits and stuff. That's all that I found that's a problem for me. Other than that I love this game! Fun gameplay and mechanics, attractive particles and effects with different zombie variations. Cash system, guns, upgrades, misc items are all perfect. I would like more guns though. Thanks for making a great game!
