I like to make silly things happen that normally wouldn't be possible if you were actually being considered decent with your diffficulty, and when taken out of context, sound extremely suspicious and/or disgusting.
The nefarious placement of everything makes it extremely pleasing to the eyes to see this fat plumber man sprite jumping around. I mean, I know plumbers, and I don't think any of them have ever encountered 73 killer plants and had to use a key to jump across them and carry the key just to survive while working on a broken pipe, I mean come on
I think GBreeze already said something about this, now that I actually read his post, but trolling the player of your level is more fun than I would ever had imagined, and I thought it would probably be aggravating, until I played an SMW hack, which the first one I played was the original Kaizo Mario. (some take this "troll" aspect a bit further than that one, though) Kaizo feels like a masochistic and sadistic type of art, one that most people would find painful and saddening to make, but fun to watch, or on the left end of the spectrum, fun and pleasuring to play, and fun to watch, like the "Kaizo lovers" that we're talking about. Kaizo triggers the "holyshitcoolbeans" reflex, and you feel really good about something.
