I was honestly extremely surprised to have found this here. El Viento was a great, though obscure game, so I was quite pleased to find even one piece of artwork regarding it.
Annet Futatabi? I always called it "Annet Returns" myself. It apparently wasn't very fun to play at all, despite what you'd think. Though outside of gameplay it looked very good with its cutscenes and all, the gameplay itself was rough, unpolished, and had all manner of problems from what I've seen. I found it kinda sad considering I always wanted to see how Sigfried's KEIKAKU DOORI from El Viento turned out, but the end result was mediocre.
