My first thought when I ran the game:http://www.youtube.com/watch?v=NqNOT8_1VBU
I'm impressed (and I wish I were this imaginative or talented <.<). I find the idea hilarious and the gameplay highly original and just fun. Also there's a surprising depth to it. First I was just hopping around, desperately confused, trying to grab anything at all. After a few tries I started focusing on the yellow fish. I remembered what I had learned in samurai school, I meditated for ten minutes, tried again and entered a state of unagi, everything slowed down and with deadly precision I started grabbing those yellow fish as if they were feathers slowly and gently dancing with the wind... sorry, I couldn't help it, that Asian theme and this hypnotizing music left a mark. <.<
Anyway, great stuff and I'm genuinely impressed by the fact how the game rewards precise grabs in this extremely confusing environment which makes grabbing anything at all very challenging at first. I'd love to see an extended and more refined version.
Edit: Darn it, and only now it occurred to me that those yellow fish aren't even the most valuable ones. >.<
