Very clever!
I did not expect you--the creator of Naked With Apes--to come out with something so quickly. Although this wasn't the first flash that had Ikaruga's duality system, it's nice to see it used for something that isn't a clone of that game.
Graphics: This is easily your best-looking game to date, although I--along with countless others--have complained about your drawings. You have some pleasing color selections and a clever usage of flash gradients. On the other hand, there are times when the color choices aren't aesthetically pleasing. (Example: Level 12)
Music: You did a better job on the sound effects, and great use of Cycerin's music. It really makes you wonder why Audio Portal musicians don't review more flash submissions.
Content: As said before, nice mix between a maze game and Ikaruga/Silhouette Mirage. You have some great bullet patterns and maze layouts going on here. Plus, the addition of keys keeps things interesting, along with the difficulty. However, it can get repetitive over time, but that's to be expected.
What's Good:
-Nice graphics with equally good color choices
-Inventive
-Fun to play
-Great music selection
-Fitting sound effects
What's Bad:
-Can get repetitive over time
-Some of the color choices are hard on the eyes.
-Not the first flash to use Ikaruga's Duality system.
Overall: Here's your nine, and I think it's high time you learned proper drawing skills from now on.
