Energy Pylon upgrade idea.
Pylons should have an upgrade level for inserting extra Blu Gloo, having a 3 level system. The same as building towers requires more Blu Gloo for its function.
An example is Movement Pylon, level 1 gets a reduced stamina consumption. Level 2 gets a boost of stamina regain. Level 3 is a boost of movement speed.
Build Pylon: Level 1, reduces the cost of upgrading. Level 2, gain more material for harvesting. Level 3, more building health.
Makes collecting Blu Gloo a bonus for playing venture or for main story.
