Hi there, I’m known as TheGaspNinja and I used to run Portal quite a bit a year or so ago. Always tuned in with SullyJHF’s streams and got a reasonably decent time for back then (00:19:22). I decided to join for nostalgia’s sake, and also to see how much has changed regarding strats and leaderboards etc. I used to be (and still am) featured on cronikey’s leaderboard with the time listed above. Hope that everything’s been alright with the community haha
