added 10 more levels and new enemies and a new tower. Higher upgrades of towers are coming soon.
changed the nature of the basic towers a little.
Cloak detectors are not a support tower which can be upgraded into buff towers (one is added so far that increases the damage of nearby turrets)
Can build a Nuke Tower (can only have 1) that requires manual firing.
Changed the format so the next level won't come until the previous one is complete.
very much a work in progress just wanted to release what I had done so far. The game may be impossible or too easy, not sure right now but haven't added all the new enemies and towers yet.
