Nice game and very well designed. You always know when you will win, so if you lose and you were in the 9th wave you can say to you, I was too close, next time I will beat it. Also I like that pillows near your "heart", so it is harder to manipulate with the mace. And last thing that I liked was slowing the time, when you get hit, so you have kill some enemies and don't die at one second just because you left 3 enemies near your health.
Also everything is well polished, good job.
