Undertale: Bits and Pieces is a remake from the original game, developed by THQ
It is a reimagined version of the game developed by @BlaizeMayes1 and Team BnP (and ported by Wanderlust).
You will pass by a world where humans and monsters live together.
The game's details are as follows:
As the game progresses, new elements are introduced in the form of Attack Types and SOUL Modes, in which the player must move the protagonist's SOUL, represented by a red heart, to avoid attacks. SOUL modes alter the color and function of the SOUL in a battle, often used during Boss battles. There are different colors that can heal or hinder the SOUL.
During the protagonist's turn, they can choose from four options: FIGHT, ACT, ITEM, and MERCY. FIGHT damages the opponent with a quick-time event. A ACT can alter the mood of the enemy or reveal information about the enemy. Using an item can benefit the protagonist. A MERCY option can be selected if certain conditions are met to spare the enemy, thus ending the battle. After the battle, you earn GOLD. EXP and LV are awarded when an enemy is killed, but neither are given when an enemy is spared.
