A bare-bones playable level at last!

Ok, after some more additions last night, I now have a basically playable level...yay!! :)

Rocks can be pushed and will fall, and now stack to make piles just like in boulder-dash.

The crystals also fall and stack too :)

Rocks/crystals do collide with the player character (the probe), but don't destroy the probe as of yet.

Warps for objects like rocks and crystals work now too, and so do the teleporters for the probe :)

Switches don't work yet, but you can collect crystals to activate the TLS beam which you then have to unblock.

Here is a screenshot of a test level:

In the level above, most of the rocks are falling down into blue swirling vortices (warps) which warp them back up to the warps above to make a never-ending rain of rocks ;)

And a video below of me completing the same test level:
