Graphics are good.
Combat feels fine, shooting is juicy enough.
Just a couple of notes...
Couldn't respawn with a key so I had to restart from the main menu.
You could make it so that if you press the "Shoot" key when you are out of mag ammo but still have reserve ammo the player automatically reloads instead of dry firing, could be an option in the settings menu.
When you run you could make the player pull her arm back a bit so there's more of a difference in your viewport when running vs. not running.
Jumping while running feels off, like as if the velocity resets every time.
Items that aren't guns, like food, clip into the walls if you get close enough which is weird since guns are exempt from this.
In "Level 1: Peaceful" I don't what's going with that opening in the canal that requires you to jump to enter, it's very inconsistent. Some times jumping normally allows you to enter but most of the time it wouldn't, I tried crouch jumping (crouch before jumping) and only crouching mid-air worked consistently. The hallway was too dark so I couldn't see anything (a flashlight might be useful) and the first time I just assumed that opening at the end was I window so I gave up when I tried to reach it but couldn't only on my second attempt I realized that you had to jump and crouch to get inside it.
I also noticed that enemies can hurt each other after one of them walked in front of another one that was attacking only for him to get instantly popped by his mate, pretty good.
