Placement: You can only place on every other row for normal towers except for rebirth towers which can be placed in any unblocked tile. Rebirth towers: blue rebirth tower boosts the damage of towers or traps above and below one row, the green tower gives you another life, the red tower deals a percentage of the enemies health. You can stack the towers but each one placed on top it becomes less and less effective. Extra tower: Once you've unlocked every row the you can press the button again and start buying a new tower that can be upgraded. Have fun
I took some inspiration from the game Defenders Depot Classic Tower Defense on Roblox.
