I like Gates of Zendocon, nice graphics and music. I don't like the momentum the ship has though, such as if you hold the up button, your ship will move up but not at a steady rate, instead it will accelerate. Not game breaking for me, but it makes it pretty easy to run into things and die.
I recommend you look at Zarlor Mercenary in a future episode. IMO there is so much detail in that game from the intricate multi-track music to the tile based graphics that have a lot of variety between stages.
Yes I plan on doing that game too, can't wait for that one!
