Hmm, this is quite fun! The enemies have a nice variety to them. The visuals and audio are very competent, especially the bullets and gore. It was a bit difficult shooting small enemies, but I managed.
While it is fun trying to move out of direct engagement and not get stuck in a bad position, moving is still underwhelming compared to shooting. This might sound corny, but maybe there could be traps that enemies can be lured into.
Also, I'm not sure if this is just on my end, but I was able to walk through walls quite trivially.
Great work!
