What program do you use for effects? I use iMovie.

I just played it but I couldn't beat it. Some of the jumps are incredibly hard to make, going under the first slide is impossible; I had to break through the lapis just to get across. The lightweight pressure plates are designed to trigger something, but players can't trigger them. Only regular stone or wooden plates can trigger upon stepping on them. I'd recommend shortening the gaps and adding rails and mine carts for the sliding instead of boats. I'll add the download here if you make it a tad more beatable. ^^
