Hey guys, I'm one of the Twin Souls: PoS developers. Be free to ask me
any question about the game or the development!
We started working on Twin Souls: The Path of Shadows with Tenchu as the main inspiration, but it's obvious they are pretty different games. This association with Tenchu has been received with some criticism, as it's really difficult to live up to a very loved saga that has the added power of 'nostalgia' behind it.
From all the different stealth games, Tenchu features the type of stealth most akin to what we are trying to achieve with Twin Souls. The feel of becoming the 'predator'. The fast movements and verticality. The gruesome but elegant stealth kills. Surveying a scenario, planning an approach and executing it. That's the kind of stealth we want in Twin Souls, and mixed with the Japanese thematic it's easy to see where the comparisons come from.
We don't have combat. When I played Tenchu as a kid I became quite good at combat, and then the stealthy approach became useless and the game became boring. With Twin Souls I wanted to focus on the fun parts and remove the boring bits; with 3 programmers we can't build a combat system like the one in Shadow of Mordor or Batman, but we can build some pretty fun stealth mechanics.
Going on with the Tenchu comparison, there's no grappling hook in Twin Souls, but we have the Shadow Leap (a teleport) to grab to climb ledges DIshonored style. There are no ninja tools, but we have a varied array of Shadow Powers that act very simmilar (attract enemies, plant traps, long range attack, temporary invisibility, etc). Finally, we have the Shadow Creation, that we think will become a really fun and interesting feature, as it's one of the basis of the game.
By the way, here's some concept art of the 2 main characters (Aragami and Yamiko), and the 1st Boss (Hikaru), click for full size:
