This reminds me a bit of killing room but I like this quite a bit more. I got a bit confused at the area with two doors since it kept unlocking back and forth but eventually realized I needed to kill more enemies in the main room to unlock the exit door. The movement felt good (especially the jumping).
Like someone else said, I didn't care for the aim lock. I'm not sure why but something about it was distracting me. I could possibly see that being helpful as an accessibility feature or for controllers through so maybe just having it as a toggle would be nice.
Overall, great stuff!
