+ INTRODUCTION
++ This document describes a game called “Shattered Sword, ” which is designed to be a simple, 2D platformer, roguelike game. The game will employ sprite-based animation, tiled backgrounds, collision detection, physics, AI, gravity, efficient memory management, render threading, and more basic 2D game techniques. +
++
TECHNOLOGY
++ Shattered Sword will be developed for the Windows Platform using the McKilla's Gorilla game engine, which is a bare-bones engine developed by Richard McKenna for rapid prototyping 2D games. DirectX will be used as the underlying rendering technology. Aseprite will be used to create sprites and tiles. +
++
BACK STORY
++ Hiro (hero) is the prince of a fallen kingdom that was destroyed by an evil monster. The monster has shattered the legendary royal greatsword, the only weapon powerful enough to slay the monster. The first piece of the greatsword was given to Hiro as the weapon. Hiro must go on a journey to retrieve the five pieces of the greatsword to slay the evil monster and bring prosperity back to his kingdom. +
++
OBJECTIVE
++ Hiro must travel the five regions in which the sword shards are scattered to collect the pieces to reassemble the sword. Each shard is guarded by enemies, and a boss that will seek to stop Hiro. Enemies have the chance to drop buffs or amulets that will strengthen Hiro on his journey. Once Hiro has obtained a shard, the enemies in the other regions will become stronger since they have had more time to absorb the energy of the sword shard they are guarding. Once Hiro has reassembled all six pieces of the sword, he will finally be able to face the final boss. +
++
GAMEPLAY
++ The game will work like a platformer, with Hiro able to run left and right, and jump up or down onto platforms and other surfaces such that we may scroll up and down. Hiro will have to be careful with the enemies that he encountered along the way. By completing each level, Hiro gains back one pieces of the sword shard at a time. After passing the first 5 levels, Hiro will be able to defeat the final boss with the completed sword. +
++ There are three types of enemies besides the final boss: +
+-
+
- Normal enemies: randomly generated at each levels. +
- Elite enemies: they are randomly turned into from the normal enemies. Defeat them will allow Hiro to gain some buff temporarily. +
- Mini boss: they are the monsters that absorded the energy from the sword shards. The player can go to the next stage without killing those enemies while Hiro won't gain any ability/buff. +
Possible buffs gain from defeating elite enemies:
+-
+
- Increase attack and attack speed +
- Increased attack range +
- Add dot to each attack such as burning/bleeding/poisoning +
- Each hitting on the enemy will gain a certain amount of shield, the shield can protect the player, and one of the buff can be if the enemy hit the shield, some of the damage to the shield will be return back to the enemy +
- Increased health +
- Increased movement speed +
+ Besides the temporal buffs above, the player can also gain permanant buff from killing mini bosses. + After killing each boss, the main character can gain: +
+-
+
- An ability of recover 50% of its total HP when its HP drop lower than 20%, beside the buff, the main character can gain the ability to heal +
