would it be possible to make negative speeds? but instead of having it go faster (as logic dictates in this case), the animation goes backward at the speed specified (-0 being the fastest, -255 being the slowest, or whatever the highest number is ZC has for that). it would help reduce the number of tiles, especially if it's a huge animation

like the fireflies in my quest; right now, they all go from left to right. with this feature, it would allow more variety in combos. other than adding more variety and tilespace to a quest, it really has no other purpose, but it would be helpful for the things I've mentioned

though, this would take a massive code change, wouldn't it?
