I've played a lot of indie games lately and have been checking out Jams like what this came from. Some games were fun and some had interesting mechanics. This definitely covers both of those qualities and could easily work as a full game. Parallelized is a casual, yet very fun little puzzle platformer, and I found myself quite impressed by the use of split screen/dimensional shifting in order to see what is and isn't around you to make progress.  The subtle changes in the music when you're in the different dimensions is also a nice touch. Good thinking.

Feedback:

• The lack of an intro paired with the music starting with a "bang" felt jarring. Not bad, but very abrupt.
• Some objects were lacking the back halves of their textures. Understandable since it's a Jam game, but worth pointing out.
• Collision could be tweaked a little, as I hit a few "walls" at the tops of some stairs and had to jump.
• Similarly, some objects had collision when they shouldn't have, such as the obelisk near the floating, spinning headstone puzzle.
• Unless I missed an activation point, there also appeared to be no ending. I assume the "end" is the treasure area?

Have a video and keep up the good work:

(And maybe do more with this. It's great.)
