Thanks for the additional levels and the new gameplay mechanics. Here's some feedback:
It's nice to see some tougher levels, with "quickly confusing" being my favorite as it ties a lot of the mechanics together. With "tata greenie" being second. And using the size of the game board to limit possible moves is a good touch.

A nice polish feature would be to display the current level you're playing in the title bar or on the bottom right.

In "up up and away" I didn't use the laser beam, I treated it as an obstacle to be avoided. As I hadn't solved "light speed" yet I hadn't realized that lasers could help solve a puzzle. I simply placed the green in a vertical line on top of the laser emitter.

Kev: Ah, maybe the wrong version of that level is packaged. I'll check tonight.

The learning curve is getting better, with teaching one mechanic at a time in order to proceed to the next puzzle.

What's the meaning behind the level name "tata greenie"? I still all the green blocks at the end of the stage.

Kev: Nice to know there are more than one way to solve the level. The way I'd intended it to be solved the green block will have to go bye bye.
