Core of Innocence is a platform adventure game in a similar vein to Castlevania: Symphony of the Night. It currently features 49 weapons, over 250 pieces of equipment, 18 spells, and several 'key items' to aid you on your journey. The mapping system is similar to that of Castlevania: SotN and Super Metroid so tracking your location and explored areas is a little easier. Core of Innocence consists of eight areas, each with its own theme of unique monsters and environmental hazards and bosses. There will be 18 quests in game to fill in the story along the way and to provide equipment upgrades to the player as they progress through the game. Otherwise the world is pretty much entirely open, only limited by lack up key item upgrades for movement such as double jump or cat form for climbing walls. Be warned though, there is some nudity in game so it is aimed towards the adult/mature crowd, but there are options to disable most of it should you want to.
Here is a video we created for our CoI kickstarter, but it shows off a lot of the current work and changes to the game. Give it a watch!
