There are quite a few games this dare based around this "control two characters at once" concept, but I think yours is actually one of better ones. There are unique obstacles in each view and the clean visuals are effective. I like the transitions between levels and the door animations too.

This is actually a rad idea!

The controls were a bit floaty but I think that helped some parts.

Cool stuff!

Cool concept. It can get quite hard.

Nice concept. Not too innovative, but good fun. And quite tough. The floatiness sometimes seems to carry over to the other direction (from right to left)
As always with easy-death-games, try to make the restart phase short!

Are the later stages randomized or is there an actual end?
