Altar Maze (Chapel)

Your goal is pretty simple -- reach the green square in the upper-right
corner of the puzzle.

Okay, so it's a bit more complicated than that.  You need to time your
arrival at the green square so that some blocks are ready to fall.

The rules are a bit tougher, of course.  It will be a bit easier to explain
this puzzle if your pretend that you're standing on the puzzle and walking
from block to block.

There's a pattern as to when the blocks fall into the pit.  The same pattern
also tells you how to move around the board, so it's pretty important.

The pattern is numerical.

And it relates to the colors of the blocks.

The pattern is also activated only after tiles have fallen down, and only the
square that you're standing on when blocks disappear is important.
