Neat little boss battle! Had a good variety of attacks and it felt fun to destroy him. The game did feel a little underbaked, however. The HUD was painfully small, and the timed reload bar which should be right above the player when its needed was stuffed in the corner (not that it was necessary as the timed reload was painfully underutilized and too fast to time for such a neat mechanic). Was a little glitchy at times with things like death transitions, and you could shoot the boss while it is still introducing itself for funny results. Still, fun little romp and I hope the birthday boy appreciated it!
