It feels like I'm really on newgrounds 10-15 years ago. Nice job.

-"LongLoaf.com is for sale"
-the music is off-putting garbage
-let me use WASD
-I'd like to see the triangle links without using them
-dying on touching locked "doors" is not pleasant, especially since the movement is "fake-not-grid-locked"
-have some checkpoints, restarting the whole level doesn't work as the individual parts aren't related
-it gets tedious when a lot of the time is spent walking to setup the same thing because of a misstep

It's fun. Skin it and it'll do well.
