I've been thinking about it since I've beaten the game, as full. And I have not had a good reason to go to the store of skills and use any of the skills. Not that I was not there once. I wanted to use some skills for fun [and Super Sonic, but we're not talking about "Sonic dyed yellow" at this time]. But was it really necessary? I felt like two Sonics was almost perfect, as they were passing through the stages.
