Gave this a go.
2D Porn Homeworld, nice. The battles were pretty simple to understand and play.
I really like the design of this thing (a fighter?). Looks like the upper torso of a mecha!
The story is quite engaging and the girls are cute. The banter between the bridge crew is great!
It's weird that the characters say 'the enemy vessel was sunk' instead of 'the enemy vessel was destroyed'. You can't really 'sink' in space unless you're near a gravitational field. Without one, you'd just drift towards the direction of the force applied against the ship plus the original heading (inertia).
Why not the right mouse button nor Esc for bringing up the save menu (Backspace is a weird choice)? And H should hide the text box isntead of Space (which should advance dialogue like Enter does).
My only big complaint is the simplicity of the scenes. Just one position?
I'd suggest giving the planets labels so we'll know they're interactable. I skipped those from the first jump because I thought they were just background...
Bug: after the battle in Sarin Eye, the text box completely disappeared and I couldn't bring it back again (full screen mode). Not even the bottom options appear (nor Backspace brings up the menu). In windowed mode, it worked normally.
Since you're using Unity, an autosave feature before each battle would help.
Typos detected!
"staring" instead of "starring"
"soldier" instead of "solider"
Should be "I'll go with you."
"your" instead of "you're"
"Scared" instead of "Scarred"
