Sure, it looks like the version is final -_-
Anyway, pretty fair map. Although there are very little spells to choose from, the variety is fair enough.
Also, the floating text from buying a spell stays there forever. There are some actions that you can use to make it look nicer.
Floating Text - Change (Last created floating text): Disable permanence
Floating Text - Change the lifespan of (Last created floating text) to 2.00 seconds
Floating Text - Change the fading age of (Last created floating text) to 0.10 seconds
Floating Text - Set the velocity of (Last created floating text) to 64.00 towards 90.00 degrees
These actions should make the floating text fade out and get destroyed after 2 seconds. The text would also move upwards like Gold Text that appears when you kill a unit in warcraft.
Otherwise, simply add more content and such. There are some tanks that cannot be bought due to gold restrictions. How are those supposed to be bought?
BTW, the Spirit Runner things are irritating. They rush straight to the end and is hard to stop when you use a slow moving tank. Some short-cut could help tanks catch up.
Finally, Chain Lightning is insane. Getting 6 of those make killing runners very easy. Not to mention that you can run and kill at the same time.
PS: Those potion things don't seem to be very useful :P
