Untitled Space Defender (semi-game jam)

Had this concept of an original XCOM inspired planet defender game, of which you can see footage as well, and I've expanded the idea a little-bit-further; in the style of a semi-game jam. This is more of a tech-demo, rather than a game, but I thought to share it regardless.

Features include:

• Simulated solar system (scaled)
• Time adjustment (0x,1x,2x,4x speeds)
• Free flight mode, with various camera adjustments
• Planet view mode
• Planet selection (implemented only for Earth)
• Orbit view mode
• Day/night cycle (Earth)

Use the following controls:

"F" = Toggle free flight mode
TAB = Show orbits
"Q,E" = Roll camera
"W,A,S,D" = Move free camera
"Mouse click + drag" = Rotate free camera
"Mouse up/down" = Zoom in/out
"F1" = Sun
"F2" = Mercury
"F3" = Venus
"F4" = Earth
"F5" = Mars
"F6" = Jupiter
"F7" = Saturn
"F8" = Uranus
"F9" = Neptune
" ` " = Time 0x (tilt key)
"1" = Time 1x
"2" = Time 2x
"4" = Time 4x
