wave-form spells

the general idea behind this is that an object travelling in a waveform looks more organic than when moving in a strict line.
So I've had a little play-around with sin waves and rotations.
the whole thing was planned as a template, but I dropped that, as templates do lack in flexibility.

creeping roots is the first spell of what could become a wave-form / snaking spell pack.

what do you think about it?

I can't test the map. Each time I click "Start game" I get kicked back to the "select a map" screen.

Mayhaps your map is corrupted?

yeah. just found out the same thing. I uploaded the map again. It should work now.
