There's some interesting tech in this game, actually, and it's all surprisingly easy to pull off.
Okay, so if you've played for more than five seconds, you know you can use your bricks as platforms to reach ladders and ledges... but you can also use your bricks to basically fly by angling your cursor 45° (give or take) to whatever direction you're moving, and walk on your bricks as you make them giving you a lot more airtime than you ought to have. Compounding onto that, if you do the "flying" trick while you're up against a wall, you can climb sheer vertical cliffsides with a great deal of patience—if you do this when you get to the area immediately before the third major instance of toxic waste (when you cross the ice bridge and enter the cave), you can actually reach the end by skipping at least one checkpoint and a bunch of tedious platforming.
Oh, and the game doesn't tell you this, but you can pee with RMB to dissolve your bricks instantly and start over... or just make fun patterns with random spirals. It's okay, I did it, too. I won't judge.
