Looks like they're working on a lite version of the game so that it can play on iPad2 again, they've apparently done that for Candy Jelly and Farm Heroes Super Saga so far.
If you want to play on PC and continue on from where you left off, it will depend if you were connecting to Facebook or Kingdom in the game. If it was Facebook then you can play the game directly from Facebook, just type in Candy Crush in the search feature and you'll land on it. If you connected to Kingdom then you can play the game from King.com, just need to select the game once there and sign into your account.
You can also link them in King.com if you wanted to have access to the other for example, just follow the steps here: https://care.king.com/en/candy-crush-saga/how-can-i-transfer-my-progress-from-facebook-to-the-king-website
