Thanks for trying the game out! The colour matching mechanic is explained in the description, that allows you to recover from overfilled columns.
Yes – if you look at my video, I use that mechanic quite often.
But if *all* columns are overfilled, the colour matching mechanic can only do anything with the additional task orbs. I mean, sure, one simply shouldn’t overfill every single column. But that’s very dissimilar to Tetris. At that point I would rather just make it automatically Game Over to have all columns in the red, rather than making player go through 30 more blocks with the hope of getting abnormally lucky.
