WAS a fun game, initially. Paid for the ADS FREE and bought extra coins. But as soon as I did, levels became impossible to beat w/o the use of multiple hints. I expect the game to gradually become more difficult as I advance in the levels (“gradually” being the key word). But first time I purchased extra coins, I immediately went from using ONE hint every now and then (1 every 10th level or so) to needing to use a minimum of 7-8 hints, at the very least, on EVERY single level. Uninstalled.
