The sequel adds better graphics, a larger, more interesting dungeon to explore, and a improved inventory screen and special attack system. The story is more interesting and we have a town with NPCs.
The progression tree will allow you to become a mage, warrior, alchemist, or a mix of skills.
Craft potions, enchant your equipment and discover secret areas, all while learning more about the cave.
And you can now step over empty cloth sacks!
The most unique and fun feature in the game, in my opinion is the fact that you have to go in the cave several times to get deeper each time using the escape wings at the right time.
All floors are randomly generated so not 1 run will be the same.
The feeling of getting further each time you enter is a very good experience for me.
After you beat the game NG+ will offer a new challenge.
Having played the flash and android version for dozens of hours I highly advice anyone who loves rpg/rogue like games to give it a try.
