Is it possible to complete Chironex - Xeia?

The level requires both blue and purple keys to get to the ending, but once you get one of them, you can't go back to get the other due to lasers at x999y997 and x999y998. Am I missing something?

I haven't played Xeia yet, so don't have an answer for you. Maybe check out mechamind90's video walkthroughs linked below.

NOTE: See reply #2 before watching the walkthroughs. They give too much away when all you're looking for is a hint.
