QB - a cube's tale comes from Stephan Goebel. It's a maze game with obstacles.
  The object is to get Your Man, the black cube, to the black square.

Features:
1. Landing on a red square will destroy the square immediately forward. It matters whence you land on it.
2. The yellow towers must always be destroyed, by landing on a yellow square, which will fire a laser. Again, landing on the yellow square from the correct orientation is critical.
3. The blue squares enable you to jump 1 square.
4. The little black squares indicate that Your Man can only traverse that space once.
5. The green square: the forward and back squares will swap places. Very cool.
6. Not shown in these images: red/blue, red/yellow and blue/yellow squares. If Your Man lands on a red/blue square with red being up and blue down, it will act as a red piece. But will then flip upside down to act as blue the next time. 7. The green, white & black squares slide 1 space. They show up in the last 10 levels.

There are 60 levels (a perfect number!). There's a lot of trial and error. Some good 'aha' moments.

It took 3-4 hours, but I solved them all.
