Reboot it again. The current gameplay style sucks ass. Everything about the current approach to its game design is wrong. Throw everything away. Start fresh.
First thing is first. Make the decision very early in development that there BE NO FUCKING AUTOMATION IN ANY ASPECT OF THE PLATFORMING OR CONTROLS. Everything needs to be manually controlled by the player. The player needs to be in control of every action and the game needs to be about the player exploring and navigatimg their way though the hazards of the level design. Players have to line up their jumps. They have to think about their jumps. Jumps will be consistent in length and distance every single time and grabbing a ledge needs to be a manual input from the player. The platforming needs to be well designed and offer thought and challenge. Not just be automated cinematic bullshit.
Second. THERE SHOULD NOT BE A SINGLE FUCKING HUMAN ENEMY TO KILL. Not one. Maybe a few can appear in cutscenes at various points, but keep human combat away. Keep gunfights away. Tomb Raider is not a combat focused game. The clearest way to make sure of that is to have no human combat whatsoever. It's a choice that needs to be made early in developmemt and stuck to. Very light combat with some animals or mythical creatures every now and then just to give the player a little bit of variety is fine, but the core of the game needs to be all about the exploration, platforming and puzzle solving.
