Impressive game, lots of polish already as is !
I really enjoyed playing through this one, it has quite a challenge but yet still manages to be approachable, i like the way you've introduced your original mechanic through the story, after one classic shooter stage bam you can phase between 2 spots to avoid getting cornered, plus you made some very clever patterns requiring the mechanic.
The only issues i had, was that ocasionally in levels where patterns and enemies really fill the screen it can have a bit of slowdown, and some times during dialogue, the arrow button on the dialogue box would overlap and hide part of the text below. But other than these this is really well made overall.
The artwork looks really nice, and the story and world is really engaging, and the music was epic and fitted the theme quite well.
Well done to your team :)
