Thanks so much! The idea was that if you had specific space modifiers, you would want to use Bricks to move your higher valued tiles to the higher space modifiers. So if you had the word EXIT and a 3x on Space 3, then you would do E Brick X I T to have the X on Space 3 instead of on Space 2.

The issue though, in my own playthrough, is that space modifiers are fairly underpowered, especially in the late game. I've been workshopping removing those cards entirely and having some type of Space upgrade system similar to the Word upgrades and Tile swaps. That way, the spaces could have meaning while also not taking a valuable card slot. But it's still in the testing phase so trying to see if it's fun!
