Super fun so far, can't wait for more maps too. I like the selection of weapons, and the level designs are well made. I just wish I could change my weapons/settings right after I die so I can head right back in, rather than going back to the title menu and putting back in all the settings I had previously.
Overall I played for a while, it's an addicting game, has good graphics and there is much to discover, I would love to see more updates and big maps.
