Does anyone the exact rules of the L0 enemy, the blue knight with red pants that sometimes gives 10xp.

For me the following happened in one game: early game a blue orb chest revealed him, and it said '0' on him. This was new since in previous games I encountered him later in the game and he'd say '10' and give 10 xp (the 0 was not visible in those cases since he got revealed by clicking a tile then, no blue orb).

I killed him and he just disappeared, no 10xp. But later that same game he appeared elsewhere, this time with 10xp, so he can move?

I fully cleared the entire board, but ended up with score 302, where normally that gives 303. I think that's related to what happened with this 0, and the guy seemingly moving.

I already beat the game to 303 before, but now I'm trying to beat it without gambling (that is no random clicks in the beginning other than the 2 blue orbs, while in earlier games I'd reveal corners in the beginning to make it much easier), and this 302 ruined it ;p

I accidentally enabled debug mode and figured out what's going on.

Whenever you click on the L0, he always teleports to an unoccupied square. Only if there is nowhere left to teleport do you get the 10XP. Since the scroll of orb uses similar mechanics to find an unoccupied square, that means it is worth using relatively early.

Incidentally, with perfect knowledge, there are at least 18 spare HP (it depends on how much XP the 1HP and 2HP walls happen to give). So theoretically you can get a score of 303 without using the last heart scroll. Without cheating the best I've done is 13 HP remaining when using the last scroll.

The only time I've got a score of 302 is when I didn't use the scroll of orb. Unlike scrolls of HP that one does seem mandatory.
