Looking for something(warning spoilers!)

[Markan]

Hello there, I'm looking for a good VN with MC that keeps his memories/experiences from previous routes, normally it is related to time loop or world reset.

Examples like this could be 

Spoiler

ChuSinGura 46+1 or Sorceress * Alive (Alive Arc)

 

Thank you in advance.

Baldr Sky is exactly what you are looking for. MC will progressively not only regain more memories of his past, but also retain some memories from previous routes, until the final route where he remembers everything.

The Tiny Dungeon series

Some of the trope that you mentioned would be hard to talk without spoiler, so I can't exactly freely recommended a few number of VN with that kind of plot twist. That said, if you're looking for some good VNs I can suggest you something like Little Busters, Muv Luv trilogy, Nine (Read the other three sequels as well because Nine is a serial VN), and Island. I don't know if you're already read those VNs, but if not then I hope my recommendations here will be helpful to you.
