Charging for restarts and undos? Lame – Marbly - Puzzle Game Challenge Review

The game is fun and entertaining, but I think it's ridiculous to charge to restart a puzzle or to undo a move. Also, a gripe I have with many games, why not make hints something earnable by completing puzzles? Would have been 5 stars, but I'm only giving 3 stars because of the price gouging.
