I'm quite fond of Swords & Shadows. Zelda and Torchlight are great choices for inspiration of your game. To me, the dungeons felt like dungeons in RuneScape. I believe Swords & Shadows has potential to be an excellent game. I also believe, if the developer wanted to, his work on this could branch out to become larger scale games, like an mmorpg (That'd be exciting, especially with the cel-shaded art style and the procedural dungeon generation.
I'd like to point out some things that could use some work:
1) Not too sure about this, but something feels weird about the movement, almost as if walking left and right is faster than walking forward.
2) Skeletons have multiple attacks, but players only have one? I'd like to see more attack styles, or maybe a dash feature which can go forward or backwards.
3) I'd love to see more structures, maybe different traps besides the ambushes. Maybe something like poison darts (affect your HP over time, 3-9 seconds), or falling stalactites.
4) Players can easily walk in a door hit a nearby chest, go back hit a different chest, and repeat the process for infinite generation of gems, perhaps you can fix this by adding a cave-in on the door after just going through it.
5) Timers: Everyone hates them, so why have them? Perhaps you can make it so upon chance of entering a room, the room becomes unstable and has a 30-60 second timer, before the cave will collapse. I'm just throwing out ideas, I'm not trying to control your game, you have to choose what your game is going to be.
Again, I think Swords & Shadows has a lot of potential, I love Zelda and I really like the concept of Swords & Shadows, so I must tell you to continue working on this game.
