The gameplay loop can be overwhelming at first, but once you get into the flow of it, it is really fun. I like that it encourages chaining kills from staggering to shotgun to sword and back to staggering. I does provide the same vibe of the glory kill system in doom 2016. I can tell this game is imperfect and there are a fair share of bugs and glitches, but the gameplay loop is solid and I am looking forward to see this game expanded.
One gripe of mine though is that I think area 2 may be a bit of a difficulty spike, you are first introduced to 3 enemies at a time, and the suddenly you are dealing with 20 in the same room, which might contribute to the overwhelming-ness especially for those who have not have a solid grasp of the game mechanics yet, myself included. Maybe reduce the difficulty of that part? Either way, great game.
