Eevee (Evelyn Woods) efd25294ac Restore the notion of an out-of-turn move 
This fixes a lot of replay sync issues with cloners; in CC2, actors
advance only one frame (1/3 tic) at a time, so when a cloned object
happens to get a turn later in the same tic that it was cloned, it only
ends up 1 frame ahead of everything else.  Since actors can only begin
moves on tic-aligned frames, even though it does get where it was going
sooner, it has to wait for a frame before moving, so the advantage
doesn't change anything.

The problem is that LL counts movement in tics, not frames, so that kind
of bonus turn puts the clone an entire tic ahead which can gum things
up.

This is still not perfect, but it's much closer.

Lexy's Labyrinth

This is a web implementation of a puzzle game that bears a striking similarity to Chip's Challenge and its sequel, but is legally distinct, and also free!

It is a work in progress and also might be abandoned and forgotten at any time.
