Sonic Eraser Routing

Controls
B, C - Flip piece counter-clockwise
A+C - Force Game Over
Start - Pause, Advance screen

How the run works
Any time you select a round from the main menu, the pieces you get are pseudo-random.  Any time you advance to the next round in a playthrough, the pieces will be in a set order unless you Game Over and return to the title screen.  As such, round 0 is random.  Ideally you want to get two quick pieces with blue spheres in them.  After round 0, the pieces will come in a set order.  If you make a mistake, you have two options.  Wing it and find a way to get thru the round, or use the round select screen to either go back to the current round with random pieces, or go to a previous round with random pieces in hopes it will be easier to complete the earlier round with random pieces and continue on as normal afterwards.

The below notes are not currently optimized.  They are notations of how I got thru most of the levels for the first time, as well as some new strategies that have been found.  A lot of these strategies were found by Shanekilz and JoeyBaby69.
