I liked the platforms. They divided the map nicely and made the roads a little more interesting. They were infuriatingly low, though.
Of course, artistically, some huge rocks and small hills could have added more terrain variety, but the problem is that in an isometric view a high platform would hide the creatures and the hero more too often.
The function of platforms is that the edge would act exactly as a wall to keep the creatures from flowing all over the place.
I do encourage having a jump animation for the hero to jump down from a low platform but to climb on his /her way up. Creatures are not supposed to be able to follow because the game is in a fantasy world that has its own rules. I was disappointed to know that the hero could not “climb” or step up on a chair because I had a plan to bring one out beside the platform to make a step. If the hero could climb up and jump down, then stairs or steps would not be needed unless there was a structure on the platform with a path that extends to those steps.
Also, platforms need not be vertical-cliff-contoured all the way around but with some side having a ramp could be a cool idea also.
Thanks.
