Fixed in 1.0.4. Dang i just saw you were faster. I had a hard time figuring out how to use if statements, lua doesn't like using them inside wickerbeast.animations at all, which is highly limiting to say the least.
Jetpack sprites however may take a while. I do not know how to replace those at all, if that is even something i can do in the first place. I'm most concerned about the code around this since i have zero lua knowledge and going through these lua files is like reading chinese. 10 years of C++ doesn't seem to help me here at all.
