Narbacular Drop is an environmental puzzle game in a fantasy setting, where the player navigates a dungeon with two interconnected portals.

The dungeon has a series of traps and puzzles, which the player must solve by moving around objects in the environment using the portals.

The player controls the Princess character who has been captured by the demon. The demon has trapped her in his dungeon lair, known as Wally. Wally is a sentient dungeon and can open holes, or Portals on his walls. These portals connect and any object moving into one portal will come out the other. Wally is resentful of his owner demon owner, so he joins with the Princess to help her escape. In exchange, she agrees to free Wally by directing his portal power to vanquish the demon.

The concept is two interconnecting portals that can be freely placed by the player. When looking into one portal, the viewer sees out the other and vice versa. The added feature of moving through the portals allows for many unique gameplay possibilities.

This portal system, combined with a basic physics simulation allows for a huge level of interactivity. Players can toss boxes, boulders, or even themselves around the dungeon. Players can come up with their creative solutions for the puzzles presented.

The portal interface is very simple. The left mouse button fires a blue portal, which appears on the wall, ceiling, or floor in front of the player. The right mouse button fires a red portal. Only one of each portal can be open at a time. This allows for a fast learning curve and low-intensity gameplay that benefits puzzle games.

Narbacular Drop is a fun, original puzzle game with unique and intuitive gameplay. Players can find creative solutions to engaging environmental puzzles using a never before seen portal system. The cartoon atmosphere and low-intensity, simple gameplay will make for an entertaining and memorable game.
