Europa rescue! - the first two levels

The second demo is here and it brings more gameplay. Launch atop the Twardowski rocket and step into action:

• Prepare your spaceship and dock Europa,
• Enter the Czechoslovak Bohemia module and restore the power.

The intro sequence has been slightly redone and fixed and more actual graphics were added instead of the simple placeholders of the initial demo. Color support has also been added as a test.
