challenge
this game has some severe balancing issues
on normal i can only get to level 3 before enemies were essentially invulnerable and leapeed across the screen to deal substantial damage before the gun would finally unholster, and having a knife to fend off the zombies is useless because the gun is the only weapon that kills from anything resembling a safe distance
and what is the point in having the ability to jump when it doesn't even go higher than the zombies or any or the projectiles
plus the grenades are overpriced
on the other hand the artwork is great in a metal slug way and the sound effects are likable
this would have been so much better if more play testing had gone into it
