As always, I'm completely unfamiliar with this game since I've only a select few Sega Master system / Game Gear games. I did like how all the sub-stages look like smaller portions of a bigger whole (especially for stages 1 and 4) except it's a bit disappointing in that they only "look" like they fit together. If you actually try for example to put together the stage 4 maps to assemble what looks like a spaceship, none of them really connect together. Of course that's absolutely not necessary for the game to be good or even just playable, but it's a nice attention to details when it happens to fit. At any rate, good job finishing this!
