I recently played the first game for the first time. It's amazing! I'm usually strictly a console gamer (PlayStation) but, as I'd pre-ordered "Awakened", I received the code for the additional content and didn't want it to go to waste. it helped that Steam had the game on sale!
Anyway, I LOVE customisation! One of the aspects of the original that I was pleasantly surprised by was the ability to edit the colour schemes of heroes and crystals. Yes, the costumes are awesome, and swapping parts—in the second game—of (mostly) the default is cool. But I would love to see the colour customisation brought back! However... if a developer is reading this, PLEASE include a value indicator (such as RGB or HSV) in arbitrary count or percentage. Otherwise, replicating a look (to match parts or heroes to crystals) or creating 'team' colours becomes impossible. Games like "Terraria" have had HUGE missed opportunities by incorporating a free form method of colour selection, and it's maddening when trying to build upon a theme and create a more personal experience. I don't know how many other people care about this, and my opinion is somewhat informed by my OCD, but I am hoping I'm not just an exception.
