I get this game's groove, and I like it. It's an arcade-style hack'n'slasher where you enter a zone, try to cut your way through the enemies in your way, and exit through the far door, to be teleported to a new zone. See how far you can go before you get mobbed and killed.
As a fan of the original Berzerk, this is a pretty nifty rendition, it really just needs more zones and some polish. A proper scoreboard would be nice.
I did hit a zone where the exit door didn't work, and sometimes it would drop me into a new zone facing backwards, so I was looking at the door I came through while enemies approached from behind. I assume forthcoming patches will fix that, even if I have to write them myself.
