I played 2 full rounds and 3 failed attempts. Which already means I spent like 30 minutes on your game so needless to say that it was quite enjoyable. Although I do have some suggestions to make:
First off: It is really difficult to tell where the cursor is since everything is black and white and there are so many particles and stuff going on.
Also it would be good to have some kind of information about weapon stats.
And lastly, I would have liked an optional "endless" mode after 10 minutes. It took about 9 minutes to finally gain crowd control, would be interesting to see how much more powerful you could become and maybe even afk the enemies using a whole lot of scythes.
