Hell.  Yes.

Graphics are probably the last thing that makes a game.  Game play being the first, followed shortly by speed, as nobody likes to play a game that has .5 FPS   But yeah, it bugs me when people complain about graphics although sadly its usualy the first thing people look to in a game

Actualy, the way i have my engine set up, it could create some horrible collision problems When block A hits block B, it changes block B's velocity, and when the engine goes to simulate block B's movement, it cant just blindly move the block, or exclude any boxes, or else moving block B might actually make it end up inside of Block A if the conditions are right. 

As for map collision, i forgot to put that on my list of things to do, but it might be tricky for objects that are wider than the tiles o.O

Its because the expression isn't evaluated the way you think it is, right now it is this

((Z=54) Or Z) = 15

because expressions are evaluated left to right.  Try adding a single ( right here

Z=54 or (Z=15

Oooh thats nice to know, that way you dont have to store random values, you can just call the random function and then use {L1-2}r

Seeding the random number generator! Simple but potentially useful

Seed->Rand

Thats actually pretty nice   Are you planning to add any other features or do you plan to move onto other projects?

I believe DiagnosticsOff does this?
