This is a very neat little dungeon game. I like the feel of the controls and you get a hang of it quickly. Unfortunately there is no music and some sounds are missing (key, door), but overall its nice. I didnt finish the boss fight, the design is good, but its too labourious, as the minion-spawns are to frequent, so you dont have time to shoot the boss after clearing them, but if you dont clear them they quickly become a meat shield for him. His regeneration is too fast as well imho.
Overall a very nice game! Well done!
