A fun little game! It felt very satisfying to blast the zombies and it got good kinds of crazy when they broke into smaller ones.
Shooting enemies was kind of hard - especially at point blank range - due to the reticle not being aligned with the line of fire. Additionally I felt the character moved and aimed too fast and made for very loose controls. If you were to continue this I feel the experience would be better if you tightened up the controls more.
Regardless that didn't take away from the good parts of the game. Well done!
