Most extra maps are supposed to be a little bit weird :)
Version 1.5 is almost done,
it is easier to understand, also the engine has been improved a lot (2x-3x faster).
I am working now on redoing the menus and tutorials, any input would be appreciated :)
On 25, try keeping 2 unicorn towers to cover the map
tachyon towers increasing the fire dots (sell and resell)
and doomsday tower around turns where the turret can cooldown while out of range.
ice laser towers up at all times is also a must :P
Your strategy is nice wads, but it sounds a lot like an exploit. Will take a look at it _
