Starting late. And with limited time, too.

From Italy LD starts at 3 AM, which is a pretty crap starting time. I woke up this morning a made my regular household stuff, then I read the theme (BTW: “You are the villain” is theme I downvoted) and had lunch while brainstorming ideas.
Now it’s 2:35 PM I will not have a lot of time to compete during this weekend, 4-5 hours today and maybe 2 or 3 tomorrow. This gives me a 6-8 hours time span to make my game.
My best idea so far is a Missile Command clone, where you actually try to destroy bases. The idea is simple enough to be doable in this short time.
If I will need more time I may get extra 3 hours by staying awake tomorrow until deadline, at 3AM, but working while being too tired usually causes a lot of troubles, so I hope to get everything done earlier.
