If you like the combination of rogue lites and reverse bullet hells (Danmakus), and the charme of retro-ish first person shooters - this is the game for you. Buy it when it's discounted, buy it when it's at normal price, this is a treat. If you're not sure, there's a demo. The game has its own charme and is well-executed. It won't win any story-telling awards, but it found its own balance, a mix that creates something unique and worth spending time with (it helps that game loops are limited, most levels have timer of 5 to 30 minutes).
