Day one is finished!
Well, I think it's all for today. My concentration is getting low. I made almost everything that I planned, but still failed to make a complete game loop (it was the plan!).
A few Cubes are locked inside the escape pod. They are waiting to be rescued, but the fuel is getting low. Ship systems are failing and can't sustain all of the survivors.
- You can jettison dead and alive cubes to space
- You can turn on and off various space ship systems (oxygen, heat, power)
- The Cubes consume resources
- Some cubes need more resources to be alive (and maybe they are the ones you can send to open space)
I still need to make game loop - start scene with tutorial and the final scene with statistics. That's for tomorrow's morning.
Also there are a lot of minor stuff (graphics, sound, music) left. I'll try to cover it tomorrow too.
