I loved the tone you immediately set with the brief dialogue and music. Your art did an excellent job of maintaining the vibe.
The controls felt off for me. I felt like a lot of movement was expected from me, and crouch was placed in a position that was awkward to reach from the general WASD movement position. I also didn't really feel the utility of the dash without i-frames, but it looks and felt good otherwise.
I also really enjoyed the touch of interacting with a giant button as the character rather than a UI element as the player.
