Feedback required - I moved the dynamite to the end of the element thread. Anything added after you import will mess it up completely.
I buried the dynamite a bit deeper by raising the terrain but I don't think it matters - I believe it is the sequence on how Joey processes the data. I learned this from Netshift (which is now defunct).
Try just playing out of the box or settling.
Here is the code:

Tell me if it works on your computer! I had no time to put a structure around it as that programming is getting a bit complex so just gently roll a detonator bomb to ensure it is on the platform. You will probably kill the Wizards but, you can blow their corpses to heaven. The cool part is the bombs are hidden.
