Thanks, edited.

So far my Blackcat improved a lot after the uniform.. I'll need to test out more compare with Gamora and the rest... Not really much female speed heroes 
antman is just average... and very very hard to farm. Need to use crystals buy his bios else takes a long time via shifters.

yes confirm 100%.. spiderman is the best male speed character in the game. Even more so with Black Spidey uniform.

you should focus on character you like..  like dr octopus or modok ,everybody hate them.. Now ,  octopus become spiderman, modok become spider modok.Who know antman will get uniform also.

u need to install facebook application first.. then make sure at settings there the facebook is logged into your account as well (theres a place to insert username and password there too).

Then press on facebook icon when in game settings.. if it says theres existing data click "no" then it will save your current data.

once on android device... during tutorial of game.. press settings and press facebook icon and viola, it will load your game.

oh then i know why d... the moment u link facebook u cant delete the level 1 account anymore.

problem is u did not use the FB one.. u linked to Apple ID and continue play on that one. Apple ID cant import over to Android.
Only Facebook ID can.

so now in dilemma coz if u use FB one (load FB) u have to start from level 1.. u cant continue the apple ID progress. You cant wipe or do anything to a game progress on a particular ID once you are stuck on it.

sorry dude.. only way is to start over fresh as FB account if u wanna buy stuffs for cheaper over at Android (crystals price is cheaper at Android - fact).

how long have u played? if just started and havent donate any $$ start all over again at Facebook. Much better for long term play. Later tempted to buy crystals how? Buy at Apple Store all in USD lei  Android all in MYR and much cheaper in comparison.
