Its fun but...
This is a very fun game but I dont like how long it takes for lives to regenerate and the ISO 8. I believe that the ISO 8 should be easier obtained it is so difficult to get ISO 8 and it costs way too much for the amount you get. I believe that you could by ISO 8 with the yellow test tubes that you find in the levels. I also have a problem with the portal I think that you should be able to cross off or eliminate the spiderman characters you have already gotten because I had 110 ISO 8 and It was wasted on to characters that I already had.
