Many thanks for the feedback guys.
At Pusga and Jisse: I have one already planned out, but I lack the time to make it. Maybe during summer vacation.
This one had just some simple stuff since the whole theme was the flail-y look of Rubber Ninjas and only required me a bit more than an hour; the actual spar I have planned has some complex and time consuming features that make it impossible for me to do right now.
At Lushsmoke: I can't get around to making an extensive hacking tutorial on advanced stuff, but with the basics of
this tutorial and some imagination you can come up with some crazy stuff on your own.
Hacking is all about creativity after you know what each thing codes on a .rpl file opened with notepad.
