Take what we did in class and build on it creatively, making it into a (small) game. Add at least two additional block types (e.g. moving boxes, rotating boxes, different shapes, multiple hits to clear). At minimum, create new two levels demonstrating the use of your new block types. Here's a hint on figuring out if there are blocks remaining here. Another here. You may also alter the look and feel of the game if you'd like.
To hand in your work, upload your unity build and link to it from your index.html page. To receive credit, it must be uploaded by class on the date specified. Label it clearly. Here is help if you need it.
