No, but personally I found it much quicker and slightly more enjoyable my second time through. First just concentrate soley on getting the different forms, then go back only after you have all of them for the stat upgrades.
Once you have the forms enemies are pretty easy, and you can spam the Golem form then revert for cheap HP.
