'twas alright
I see what you tried to get out of this game, and for the most part, you succeded. However, for majority of the time, the goal is simply to move your "helmet" near the closest zombies and spam Z or X (doesnt even matter which key) and you probably will win with 99% remaining health. It becomes less a game of precision, with the multipliers and the coins almost always unexpected and a result of chance, and more a game of button mashing. It was fun, for a couple of levels at least, but boredom came with the unavoidable repetition.
