I need Isometric Exploration Tablet Game

I am endeavoring to build an 2D tile-based isometric game, primarily for Android and iOS tablet devices. It will be built in Unity 3d v4.3+, with C# scripts, to maximize platform compatibility.

The player can control a character that they can move by clicking on a tile, whereupon the character will move to that tile. The map itself can be randomly, procedurally, built from a number of predefined rooms; the engine can fit them together by lining up their doors.

A good point of reference could be the Doctor Who Google doodle.

As the character enters each room, the game may reveal the contents of that room. These are also randomly evaluated, and may be items on a tile, which the player can click on. The character will then moves to the closest adjacent tile and pick it up. The item will be included to the character's inventory if they have room remaining.

The character's inventory is shown as a carousel of items along the bottom of the screen. The player may tap/click on an item to use it. Once used, the item can either be lost, or it will trigger a cool-down timer before it will be next used again. Item effects will vary.

The player will also drag it out of the bar to drop it. Some items can be weapons; the player may select these items to be their equipped weapon. This user interface bar can also show the character's health and energy.

When entering a room, it can also reveal to contain an enemy. The enemy will start to move slowly towards the player character. If it reaches within a number of tiles distance to the player character, within range of its attack, it will start to damage the character at a set rate. As long as it has line of sight to the player character, it may also continually drain its energy.

The player can either tap on the enemy to attack it with their equipped weapon, or move away. The enemy will stop chasing the player character if it loses line of sight for a specified duration.

- 2D isometric tile-based game.

- Player controls a character they move around by selecting tiles.

- Map is procedurally and randomly generated from a set of predefined rooms.

- Entering a room for the first time will reveal its contents, which can be items or enemies.

- Items will be added to inventory by selecting it so that the player character moves to it and picks it up.

- Items will be activated from inventory, triggering an effect and then is either discarded or incurs a cool-down before next activation.

- One weapon can be selected to equip.

- Enemies may chase the player, and attack when adjacent.

- Enemies that lose line of sight to player will stop chasing after a while.

- All elements must be extensible and configurable, so that new items, enemies and rooms will be added easily.

I will be working with a graphic designer on art assets, so placeholder art may be used during development.

Skills required are C# Programming, Game Design, iPad, Unity 3D
