The first time I played this game, this is the solution that I found. It felt like an alt since I never used the lower right hand corner of the level, which I later verified watching the run by RbdJellyFish. This solution is slower than his by about 4s (I made a few dumb errors, I feel could have shaved off 2s off of this run), but I like it better since I bet I'm the only one that's discovered it.
