Connector 1-2: I think adding a point_spotlight + ground light prop would make your hologram look much better and can sorta guide the player as well.
Connector 2-3: Add lights and or detailing to direct the player upwards.
Jump 3: Not a fan of clipping the sides on the 2nd wallshot.
Connector 3-4: Add lights and or detailing to direct the player upwards. There is no point of the dark empty void underneath.
Connector 4-5: Mostly fine but the dark textured ramp after the water makes it unbearable. It'll be much better if you continue to use the light gray texture right next to it and add more lights. Please clip your stairs with blockbullet2 at the end.
Connector 5-6: point_spotlight + ground light prop. Add more light.
Jump 6: Please try moving this corner back, it's annoying when your rockets get eaten. (

Connector 6-7: Change the clip brush to blockbullet2 at the end.
Jump 7: The rock displacement walls are shootable with rockets. Please fix.
Connector 7-8: Add lights and or detailing to direct the player (which way the hole opens to).
Jump 8: You need to fix the first two walls. The nonade is annoyingly close to the wallshots which basically share the same texture. It's probably best to just make the walls taller. (

Connector 8-9: Change the clip brush to blockbullet2 at the end.
Connector 9-10: Maybe add a light to your secret cow. Change the clip brush to blockbullet2 at the end.
