Flawless as usual.
I absolutely love these shift games since the first one.
I enjoyed the music, along with a timer it set a nice fast pace feel to the game (for me at least). It was not an easy or a hard game, but was mind blowing enough to still give you a good sense of accomplishment when you finished it. I thought the use of two to three characters at once was extremely well done, and I was worried it would get annoying or bothersome.
I very much look forward to future flash submissions from you.
