I have never played a game quite like this. The basis of the game is that there is a town near this dungeon, and everyone who goes in the dungeon basically dies. So you go to the town and start a guild. In the guild, you can basically make as many characters as you want and you get to pick from several classes, fighter, healer, mage, all the basics. From there, you can take up to 5 into the dungeon. As you take steps, you need to mark it out on your map where you see doors, fountains, walls and other such things. At first, I thought this would be repetitive, but it kinda draws you into the game and makes you feel like you actually are walking through an unknown dungeon. You can unlock two more classes later in the game, but I never really used them because I stuck with my party of 5 throughout. The game was going great and I was at the final level and then I fought the final boss. Since most of the game had been easy, I figured I'd breeze through him. Boy was I wrong. This guy totally dominated me. This turned me off from the game for a few weeks, eventually I picked it back up, did some leveling and was able to beat him, but to play through a game and get dominated by the final boss was pretty rough. The only flaw I saw with the game was the final boss. Everything else was great.
