Using W to Double Jump was frustrating for me. It mad the first level difficult. Its OK with practice but still :-) Regardless everything else is a really good game with good ideas and fit of theme plus nice art and sound to boot
i can understand the frustration of W as jump, but during our playtesting we found it the most comfortable. I'm glad you enjoyed it!
W for Jump is great but the double jump felt awkward to me for some reason. Anyhow excellent game.
