Great but..
Man it was so cool the first time. I died and figured it was my lack of skill. But really the enemies consistently spawn very close to you, and many become unavoidable. Then, it costs a ton to heal yourself, and you end up spending so much on health, your weapons become incredibly obsolete within the first time using the health upgrades. Everything else was awesome, and I loved the different enemies. The big semen monsters were my favorite.
