5 minute achievement doesn't unlock

...and I don't know how to turn it off. Please, fix!

Nearly complete black puzzle pieces on a nearly complete black background... are not really visible. You know? Do you even still test your games before spam releasing them?

You guys really need to add a little gloss to the pieces, especially around the edges, having them be completely black really makes it difficult to focus on then when they are on top of others and when adding them to other puzzle pieces, my eyes get really tired too. Something like this would be nice: https://www.createjigsawpuzzles.com/pops/puzzle-finish.html I own several of this puzzles of yours but i'm seriously doubting playing them as they are now......
