The right half needs minor tweaks, the left half needs major tweaks. When you've rearranged the circuit correctly, one green bug explosion is all that remains.

This is the final evolution of level 2.05. The more you glitch a drone, the easier it is to slip through the gap you just created. Take your time and use your glitches.

You will wish you were playing 5.03. It is VERY important to glitch and explode as many drones as you can. Get on the board right away.

There is always one tile that eludes the infection. Figure out how to wrap the right edge twice and you'll be golden. Don't give up!

Drones.. come together on the right side, then left.. Retreat to the top. Work on the opposite side.

This is the hardest challenge achievement.

There are four safe spots on the board. Make sure you get to one when the drones come by. There you can think as long as you need to.

Kill the blue drones using your glitches and the wall of indestructible drones. Once they are off the board, you can keep them from returning by placing glitches at the edge of the board when they are respawning.

This is a GREAT puzzle. You beat it in the same manner as level 4.03. If you don't count tiles, you will not win. The magic number is seven tiles.

Work from the outsides to the inside. Isolate each encrypted tile row, by turning the red tiles away from the row. Take your time. I'll post a video walk through to explain how to beat this level in the near future..

Take your time. Drones can only hit you from two directions. Dodge back and forth on a single axis.

This is the second hardest challenge achievement, but it was a lot of fun for me.
