The Killing Machine doesn't reinvent the survivor-like formula, but it executes it with confidence. The SFX and music fit the atmosphere nicely — I just wish the music was a bit louder.
Weapon and upgrade variety is solid, with a good sense of balance. I had a lot of fun with the Axe + Hammer combo in particular. The core loop is tight, and the UI is clean and readable.
All around, this is a good one.
