The core gameplay and visual design are pretty good. Your mileage may vary when it comes to retro pixel art but the homage to Wolfensten 3-D/DOOM era design did land fairly well for me. This limits the shooting mechanics a great deal as you're not dealing with real 3D space and there is zero verticality but the developers layered in some nice RPG leveling mechanics to spice things up. I played for a number of hours before realizing that there are a limited number of lives. Progres resets to the first level once those lives are gone. I don't think this is the right choice for this style of game and there simply is not enough communication about this when you're first learning how to play. Finally there are minor performance issues as other have mentioned. I simply bumped down the overal quality to Medium and saw a dramatic boost in performance without really much in the way of visual degradation. The developers lavished much attention on various retro display filters and it's debatable if that was a good use of resources for them.
