LoI's short length is ironically another plus.
BING BING BING! We have a winner. I think one of the major things that killed CoD was how each area was too big for it's own good. In each area, you could probably fit in 2 areas of LoI. Actually, in CoD, they SHOULD'VE fit in more areas, but cut the size down a bit. Particularly in Some of the places like Infinite Corridor and Dracula's Castle(which seemed to go on FOREVER). What they should've done was break the areas down to two or more(in Dracula's Castle's case) smaller areas, each with their own bosses. For instance, Look at Mortvia Aquaduct and Mortvia Fountain, which are basically two parts of the "Mortvia Aquaduct". You have the first leg, the suspended water channels, then you have the final leg, the aquatic ruins. There should've been a part where you'd fight a boss, or mid-boss at the end of the first part so you could pass onto the ruin area. Dracula's Castle should've been composed of MANY areas. Well, maybe not as crazy as the other games, but you could've fit 3 good areas into that final dungeon, along with more bossess(C'mon, it's Dracula's FREAKIN Castle!!) that were spread out. Easy as pie, first area of Dracula's Castle could've been the Entrance/Outer Walls(where you fight a boss), then the second area could've been the Dungeons(where you'd fight another boss), then the Upper Area/Keep(where you fight Isaac, Death, then finally, Dracula). IMO, that would've been more like CV3. CV3 had a messload of bosses. I was hoping CoD had more of a feel of CV3 than it actually did, and that let me down. SotN, it's a sequel to RoB, and it has some of the RoB feel. Some familiar backgrounds and enemy sprites. CoD to CV3, they really didn't have much returning bosses from CV3. I was hoping we'd see something like the Skull Knight or Leviathan. At the least, LoI showed Medusa as a giant floating head. That kinda took be back to CV1, since that's basically what she looked like, and the intro is kinda the same(She starts off as a giant stone bust, then comes to life). A little nostalgic.
