while doing a messed up inbounds run i decided to give up and do random stuff in the glados fight, i put a portal on the highest point possible in the map and then jumped from it into another portal so id get launched on top of glados and then glados started saying ending lines and when i jumped down the rocket turrent was closed, did that count as beating the game? (i have video proof, will give link when it uploads)

Did the game end or was glados softlocked? Theres a difference

Did you see the credits ? Yes/no You have your answer.

nope:D

Then you didn't finish the run

Did the crosshair disappear?

nah only glados bugged out and the turret stopped

Then the run does not count. Sorry!
