It felt really good.
Really liked the theme, would love to see different locations that this setting will provide.
Pain stunning is either from any shot (simple gunman) or you can't (dogs, cultists). Would love to not being able to stun whole squad of goons with just a pistol.
I liked how good it played, movement, shooting, map layout of 2nd level.
Projectiles are fair, yes, but if all enemy's shoot projectile, it feels too easy. (You can make pacifist run in 1st level blindly)
Not sure why do you need to always have your weapons visible on the left. I would love to know their ammo count thought
Your shotgun shoots 2 bullets per click, if you have 1 bullet you just cook your shotgun and waste ammo.
Stairs from the road to the fountain (black ones) on second level are not climbable.
If you jump in a train you fall under it's floor and can't get up (until it stops)
