Very good run and gun game in style of Contra or Metal Slug. If it was on old arcade machines You would feel insert one more coin to continue play it. Game is pure action, no pointless fillers. Awesome music is pumping all the time. Graphics is top notch pixel art with many monsters on screen and giant bosses made with many well animated parts. There is lot of nice small details on stages, well animated backgrounds, flickering lights, small destructible stuff.
