Few things to add- (Shop) Statistics, Extra life (4 lives) and/or score bonus x2. Also you could make a 'Sandbox mode' Letting you stack as many cakes as you want and start the king when you want. These are some possibilities you could add... Most likely you wont see this comment (Juicy beast) J:
@Bobsson, that would be a total waste of money since every new level of elevators cost $5000 and the way your going is you would have no more money with 5 rooms ._. (Just saying)
Few tips I thought might help:
When you use stun spell use it on the tower with most area control, that way all of your units
can heal for a little---
When using the heal spell use it in turns and try aim for most units, a way of saving up mana---
What type of tactics I use is : Stun spell on bog towers (if not other area control towers) And my unit pattern is ( 8,7,7,4,7,7,4,7,7,4,7, etc ). Hope this helps
