So it's 3:30am and I'm REALLY tired, but I'm releaved to have completed my 3rd LD:

Surface Defence

Controls:
Z: Turret (shoots enemies)
X: Fishing hut (makes money if there is fish)
C: Observatory (produces science, that accelerates the construction of the shuttle)
Space: Place building ( sorry for no left click..)
Shift: Delete building

Gameplay:
- The goal is to fill up the blue science bar and escape earth. This can be achieved via defending the island from the evil from beneath the surface.
- But thing cost money; Fishing huts only generate money if there is fish on the local island (Represented by green bar).
- Observatories produces more science per second.

Known bugs:
- title menu won't start the game until you have looked at the help screen.
- the game uses "setInterval()" to spawn monsters, witch runs on actual time, but the turrets does things every frame. If you have a laggy computer, this results in the turrets shooting slower than the game spawn the monsters and it's unlikely for you to win the game :(

Please comment! :)

And as always: HAVE FUN!
