So, I completed the game yesterday and what annoyed me the most is the progress not adding to 100%.
This really destroys the overview of your progress and finding the missing place to the last location or red chest or whatever.
Additionally it would be cool to have the name tags of the planets/maps being a progression bar that fills up with a different color. Better visibility.
Lastly, please highlight the entry to cistern of slaughter and the other battle arenas. It’s a pain to find those, if you go past them the first time. Especially cistern was completely under my radar because no other collectible is even remotely close to the entrance.
