Who can help me with lock/unlock and hint/coin systems?

My kind friends I boat an asset in asset store with some issues. I am not a good programmer (maybe I'm not a programmer at all), and a can't fix the asset. The asset that I boat not ready to publish asset. It has not lock/unlock and hint/coin systems. I can't publish it without lock/unlock (at least) system. Please, please, please help me. The asset developer deny my asking (they have not a time). Help me please.
The asset named Word Search Game.
My email: pocboz@gmail.com.
I'll send you the asset to fix it and helping me.
Thank you, thank you, thank you.
