good job. I had some trouble keeping the mouse on the screen and aiming. this game felt a lot like a rising mental state game. after my first respawn the wrath did not reset. So if on your first play you attain 100 wrath you keep that unless you reload the page.
I liked that the basic environment could be used to circle around and keep enemies at bay. It did not appear that the enemies could not damage each other. Also shooting the weapon feels as if using a bolt action gun taking about 1-2 seconds per reload.
The distinct colors between you and the enemy meant i never lost myself in the crowd of enemies. Which is good. The ai... i thought was suprisingly good. It was actually fairly smooth watching the enemies move around and follow you. Reminds me of a flash game i used to play on Ninjakiwi.
For a game made over three days i'd say you did really well.
