I can't speak from experience since I played it on an A5 device, but it's running on the Unity engine, which isn't that taxing, thus any lag is probably coming from what's being rendered rather than what device it's running on. That being said, the framerate on A5 devices isn't great, there's a fair share of jitters and jumps, so don't expect a perfect framerate on your 4th gen device. This really doesn't affect gameplay that much though, it's a slow paced game anyways.
The game is quite long, it'll definitely keep you busy for quite some time, then again it depends on how long it takes you to solve the puzzles. I don't see much replay value in it though. It's a puzzle game after all, so once you solve the puzzles they'll be the same the second time through. However, there are 18 secret glyphs hidden throughout that unlock an alternate ending.
The whole game is open to exploration. It doesn't force you to go anywhere, but directs you where you need to go with subtle environmental queues. It linearly guides you to hub rooms of sorts, in which you can choose to complete the puzzles for that area in the order you please, but towards the end of the game you reach an area that lets you teleport to the areas you've previously gone to, helpful if you want to unlock the aforementioned alternate ending.
Regardless, this is a game you'll want to play. It creates a chilling and artistic atmosphere, and will occasionally blow your mind. It's really amazing how complex some of the puzzles can be, even though all you do is walk around. The only way you interact with your environment is either by pushing things, standing on things, or simply moving. But it does things with that that you didn't see coming. Think Antichamber, in the sense that you can't always think by the logic most games abide by. So yeah. Get it. It's good for ya.
