Hi Friends! Small game for coders have been added at my site: Space Invaders Automation

If you have, perhaps, 30 minutes to spare, I invite you to have fun with it! It is to be coded in Lua, but don't hesitate — language is simple (similar to Python) and we have small introduction, so you'll be an expert in 15 minutes — and can write reasonably good code in another 15, moreover there are a couple examples :)

The goal is to defend against aliens at least for 60 seconds. Current "standings" are (only 3 participants yet):

tzyLee         417 seconds
gardengnome    162 seconds
TestUser (me)   63 seconds

Many thanks to gardengnome for proof-solving it — actually it was he who suggested converting it to "challenge" format — so now you can compete, whose program stand longer!
