I like it so far, but I keep getting killed by the first zombie that I meet, or I have no idea how to interact with the machines. The manual also is conflicting, saying that left and right brackets switch weapons, but this actually switches radar targets, along with some opions not being translated to English (the biggest culpret being the controls menu) however, it is still a good concept. I also don't know how to check my coins, with every machine saying not enough coins. A tutorial mode that teaches the aiming mechanic, especially if you're going to try for verticle aiming, would also be useful.
