For someone getting introduced to a language it's ambitious, but then again that's how I would've done it. First get it functional, then you can improve on it. Not sure what the rest of the code is but I see a
Code:
PArkanoid = ^TArkanoid;
in the code, and this could probably also be replaced by a class. If it's already a class, then you don't need the PArkanoid type, as a object reference is already a pointer of sorts, so ArkGame can be of type TArkanoid, just assign it your main TArkanoid instance.
