It's new....
The concept of killing off islands with a monkey demigod is pretty darn original. And I, myself, find it hilarious. But, then again, monkeys are always hilarious to me.
It is rather easy though, provided you remember which isalnds are immune to which powers. If you forget, though, you're in for it.
The sound on here's pretty catchy, and it makes me think of Who Wants To Be A Millionaire. Very interactive indeed, but not that great on the graphics. But, you did say it was around 4am you came up with this, so I forgive it..
Overall, it's the original kind of game that I look forward to. I want to see some more creative games like this in the future.
