Part 1 is probably my least favourite, I just dont like monster sacrifices as a summoning resource
Part 2 is cool, experimenting with the different mechanics at once is cool, except the Gem cards don't seem particularly fun when you only have 4 spaces to summon in (as showcased in the very final duel of the game).
Part 3 is my favourite, I like the idea of exploring a 3D area more than just moving across a map in part 1. The upgrades you get are funner, and I just prefer traditional mana gain.
