There is the 'automatic victory' bonus objective, which needs to stand out more then. I'll have to mull on that a bit.
It would make sense if they at least needed line of sight to the field they're projecting.
A max distance would also make sense.
I've thinking about different 'spells' for the snail wizards to be capable of casting and how to integrate that into the interface.
Thank you for the calm piano music suggestion and the improved snail drawings.
