Fourth update, it is progressing :-).
2 new maps implemented in the fourth zone, the 21 and the 22.
2 new types of power node:
-Money node: increases the money reward of enemies killed by the tower above it.
-Bank node: at the start of each wave, provides an amount of money equal to the level of the tower above.
The enemy encyclopedia now also displays their rewards (XP and money).
The system now registers the best difficulty with no life loss per map (not shown at this time).
Finishing a map without losing a life increases experience received by 25%.
Improvement & balancing:
-Improved enemy rotations at 90° angles, and corrected the orientation of enemies on certain parts of the path.
-Increased power of most power nodes.
-Slight increase in the experience required for the player to level up.
-Reduced boss rewards (from 400 xp to 300, from 40 money to 35).
-The shield effects are slightly more transparent.
Bug fix:
-Fixed a small visual glitch that prevented a tower from reverting to the base color when under the effect of jamming orb.
-The "Super" and "Limiter" nodes now affect the penetration of towers in addition to other characteristics (as described in the encyclopedia).
