While it's not winter/spring -- at least in this part of the world -- here's my entry.

It's a game of asteroids, that at the same time encourages the player to learn their basic arithmetic skills. I didn't write all of it, as some of the code has been recycled from the sample Asteroids.kpl. But it is extensively extended with multiple levels, multiple asteroid sizes, multiple lives, sound effects, high score persistence, shields, and of course the maths feature.

There are some object features I have used (such as Constructors) that are not officially supported by Phrogram. But I find them very useful. I'd love to also have Enums (because they produce better documented code), and Generic Collections with Iterators.

Good luck to everyone entering!
