0.1.0 - Two new levels + bugfix

Hello, Thanks to your feedback, I've been able to fix some weird behaviour with moving lights, and as a bonus I've added two more levels.

The first level will be played before of the first one from previous builds, and includes a small tutorial with all of the game's mechanics.
The other level added will be the last one, and it will use mechanics from all of the previous levels.

I will also add a table to the main game's page with each level and how many movements it takes me to complete, in case you want a reference.
Cheers, and keep them Un-LIT! ;)
