Grinding is one of those things that can grate on your nerves, though in the case of some games it can work. Unfortunately the number of titles where earned progression through repeatedly running up against a brick wall, with the plan being that you’ll slowly improve your core skills and get further the next time, is rewarding is incredibly short. You can easily count Deep Space Rush in the not-so-good pile, with one of its biggest problems being that even when you are able to afford upgrades they’re so lackluster that your time feels wasted. Bland and uninspired platform shooting awaits, with the highlight being weapon power-ups you can pick up along the way (which are generally what you’re upgrading) but those lack in diversity or interest. Jump, shoot, dodge, shoot, pick up power-up, shoot something slightly different for a short time, jump, and shoot some more. It’s all grind and really no reward, and it’s tough to recommend.
