Entirely Pure Virtual - Severe. Not too hard when you know all the shortcuts and ch8 bug locations.

Finished Chapters 6-8. All enemies eliminated.
All 8 bugs were fed to the GOD unit.

Mindthunk patched out the bug I found, allowing me to collect Clean Sweep.

Cleared chapter 5.

Gave up on trying to get the remaining Bugs into the GOD unit and finished the game.

Playing on Strict, trying to complete without detections.

In the middle of clearing out the CRS facilities. No longer proceeding detectionless.

Ctrl Alt Ego is now 100% complete.

Attained Towering. Kept trying to clear Mum VS Debugger on Strict but I can't find a way to progress. I have no way to get the Bug past the Dad. Mum doesn't do enough damage on strict.

Looked up hints for Severe Rocket Surgery. Also learned about a Debugger access key that allowed me to clear the Debugger speedrun achievement, I already found the route before hand, just didn't know about the key.
Failed to bring the BFC to the top of the tower. It exploded when I tried to shift it. I'm just going to try it again on easy.

Completed Secure Rocket Surgery, Four Big Fat Crates, and The Tower, all on Strict. I'm stumped on the remaining two.
