Notice the game name. Refraction. Of course it's not about refraction. Maybe we can look at the title like this --> re-FRACTION. It speaks for itself :)
To reset all of your pieces (in levels with lots of pieces) click "menu", "level selection", and then your current level. This resets to a fresh trial.
the upgrades were kind of lame - same things as the previous but a different color -_-
it was also longer than it need to be, especially the last objective
also the fact that the weapon maxed at 12 after about 4/10 min. made the time go really slow...
