nensondubois, what exactly does that code above do (Give clouds, large and small mountains, etc brick block properties)? It sounds interesting.

Ah, the code basically transforms all standard objects into breakable bricks without appearing as an actual brick. I made a video, it's really interesting and adds a definite unique gameplay experience.

Jump through blocks, etc instead of hitting only on first life (the game has a byte setting to allow you to jump through objects instead of hitting them. Even weirder is that the game keeps track whether you've died or not and disables the effects if you've died and only reactivates upon resetting or if you get a game over. This appears to be related with player's size state and is not a debugging function.
ZAVPZAPA

Always jump through blocks, etc instead of hitting
