On the good side, environment is good, everything aside of jumping feels good.
On the bad side, it feels like enemies have inconsistent HP, sometimes dog dies within a second, sometimes it evades for good 5 seconds, might be spread of the gun, but still feels off. Headshots don't seem to be a thing, that is a must have.
Music is good, not sure if it's yours but it matches both game and style you seem to be going for.
