A mildly entertaining shooter was what I came in expecting, but I stuck along longer than I thought I would. I played the game solo up until about wave 5. Most times I took damage was to an enemy behind me. I would suggest an audio cue for when they're in close proximity to the player? just shooting in the dark on that one. I believe there are some invisible walls behind some of the rocks? Not sure as to why, but I'm going to assume its there because players get stuck in the map's geometry? Just curious there. The map and skulls look nice, but some more enemy variety would give this game a bit more replay value. Right now there's no motivation to boot it back up in the foreseeable future, but if there's a major update in progress let me know!
