Q: When we play Looney Ludo (Martian Coasters) with five tiles, do the “arms” of the X shape connect in any way?

A: No, spaces only connect to spaces that touch directly orthogonally, so, yes, at the beginning of the game, the center tile is well connected, but the others are a bit isolated. Remember, however, that because the tiles will be moving around during the game, the whole board will end up in different configurations, so the connection imbalance is only temporary.
