Portal Panic

Portal panic is a track with a Dark green background,A green path,Ponds and holes, And portals

Bloon's path
The bloons follow the green track,Start from the top right(Where the S is located) And when they reach the bottom,Turn right and follow the curve and into a red hole, The path dosen't End there, As when they enter,appear again in a Yellow hole(The first and second portals)and continue to follow the green path, Split on a lake(Where you can put naval units)And rejoin near another yellow portal, exit out of a blue hole(The third and fourth oprtals) And go straight Down Where the path ends

Tower placement
Land towers can be placed anywhere Except the black border,The cyan and the black holes, Naval towers can be placed on the cyan parts of the track and the black holes are space

Secrets
If towers are place on a portal and a bloon goes through it, The tower's Darts can harm the bloon Considering the fact they are out of range, It is like the range is extended

Simply put,

PROJECTILES OF TOWERS CAN GO THROUGH THE PORTALS
