I LOVE the graphics, I also love the smooth gameplay and movement.
The enemy concepts (one shoots, one follows and damages, one knocks you up) are pretty neat! They're well-designed and look nice and threatening.
The gun model is also really nice even though it's simple.
However, the shooting isn't as smooth and fast-paced, the projectile isn't fast and that mixed with the fact that you gotta hit their weakspot makes for a bit tedious experience.
Overall loved it and had fun playing it!
