Zwei is definitely one of Falcom's weaker games, but it's super charming and the music is fantastic. It has a lot of cool ideas like switching between different types of elemental magic or controlling two characters at once, but the actual gameplay is only a step above Ys II in terms of complexity since it has an attack button. The dungeons are all just straight corridors with larger rooms for combat without any of the platforming found in games like the Napishtim era Ys games or the puzzle-solving and backtracking of Xanadu Next. The only dungeon that ever actually has you go down a floor is the final one in the game, and puzzles never go beyond just pushing things around. I know there's a bunch of stuff I never touched (the optional level 20 and 30 dungeons, the hidden dungeon in the ruins, and whatever's under the oasis) but I really have no desire to go back and play more of this. I hope Zwei 2 is a little more involved since there's definitely the core of something really cool here, but Falcom really didn't realize the potential this game has.

I had more fun with Typing of Ys.
