I like the general idea you had here but ran into a lot of issues.  For starter I get about using the other dimension to move around but I had it where when I was in the purple zone, if i try to switch to the other zone, it be in a place where there is no platform and that made me switch back so I started over a lot.  I did enjoy the choice of music you had going on here.  It seem like the top zone didn't have many platform to it.  Also there was a point where there is no collider and i fell thru the floor right here.

Good concept) But it is realy hard to navigate. Also i was falling through some panels.

I dig the look of the game. With the frantic music, it gives a great sense of urgency that the character is always running.  A little difficult to navigate sometimes. I was falling through some panels - I think, and hard to know what I'm shooting to land on each time I switch.
