Awesome game! The graphics, sound and overall theme may be simple, but they invoke the old school charm of an early arcade machine, which is a plus in my book. The controls were simple, and while game was difficult in some spots, it never got frustrating.
My only complaint is the final battle.

Honestly, I really expected the king to have something more impressive than just having you go through his four bodyguards again. They're great for a warm up, but I still expected the battle to have more 'oomph'.

Regardless this was a well crafted game, and I hope to see more like it.
By the way, just out of curiosity, would you happen to be planning a sequel?
