You have to build defense towers in Portal TD: Tower Defense, a tough tower defense game with a retro pixel look.
The goal of this game is to stop the monsters on each map by putting your barriers next to the road. The bow, the blade, the staff, and the rune are the four types of defense buildings you can put up. They will attack the monsters first, and then the rune will pulse with frozen magical energy to slow them down. To put these defenses up, you need coins, which you can get by killing monsters. You can also change how your shields work in different ways! You can raise their level and even make them better. You can change the order in which they are targeted. You will need to fine-tune your defenses because these monsters will attack in waves, with each wave being harder than the last. If the monsters get to the end of the road, you lose the game.
Have fun and good luck!
