If you just want to kill some time with little to none data usage then go for it.But this is always going to be a bad game as long as they keep manipulating the game against the player. The rocket for example, is no way random. 80% of the time the direction would be the opposite so you waste steps creating it. The entire game is nothing about strategy. When the program decides you should win, nothing can stop you. But more often, it makes sure you need to use items and coins to pass a level.Lots of gimmicks have come and gone, but they still keeping the most boring shell and mole for thousands of stages. Why? Because they are the easiest one to make sure you lose.
