Loved the music, was very fun. think i almost got to the end, believe stage 8 or so.
Definitely gonna retry soon so i can finish it

The game was really fun to play! I love the "mirror" world idea, it was really fun to play.

The only thing I didn't like is that the application window was very small, and I was unable to change it. Aside from that, the game was awesome! Keep up the good work!

Game runs now fine! I was a bit annoyed at the postage stamp size screen, but Alt-Enter to fullscreen mode worked, so that's not a biggie. Awesome sound and graphics and a great idea! I got stuck at level where there is more level to be seen on the mirror side player, but I couldn't figure out how to either a) change the camera to the mirror player, or b) figure out the correct movement patternt without seeing the mirror player. Maybe the 3rd item would help with that? The black dot? However, I couldn't activate it so maybe I'm not understanding the game mechanics correctly.

A solid submission nevertheless, good work!

Unfortunately can't run the game, crashes for me with a 

as per the instructions, made sure all the files were downloaded and extracted properly, and made sure windows doesn't flag it as a virus.
