Maybe if you put some upgrades in it...like maybe more axes or stronger health. Its good though

Cool game man. I would just decrease the frequency of the health drops. Or maybe increase the mob spawning rate. I deliberately let myself die because the game was taking too long. Other than that really cool :P

Gets repetitive after a short time. The levels feel the same. If this had upgrades, maybe to the point of damaging a ship, it would be much better
