Cube Decider Switch NSP Free Download Romslab Cube Decider is a simple little game and one that is not hard to understand. That’s probably just as well, considering the game hasn’t a tutorial or instructions. You play as a cube, with arms and legs and an all-important sword. Throughout each of the fifty levels, the game’s goal is to weave your way through a stone wall maze to the exit. Numerous enemies are in your way, as well as spiked traps and fire pits, so you’ll use your logic skills to get to the exit. You’ll collect power-ups, upgrade your stats, and decide whom and when to attack in the maze. ROMSLAB.COM BEST SWITCH GAMES

As a cube, you start each level with default stats values of one damage point, five health points and no armour points. You choose which stationary enemies to attack and in which order. The cube enemies also have a sword, and some have a sword and shield. Sword and shield enemies are harder to kill than their none shield counterparts. Basically, your task is to attack the enemies in the right order to have enough health and armour to make it through the level to the exit point. That makes Cube Decider a puzzle game in my book, so I’m not sure where the RPG tag is applied to the game.
A Cube with a Sword
Let me explain why I say that. Your cube picks up cards in the levels, but the cards don’t do anything, such as give you an extra life or add to the gameplay; the cards are just collectables. Your cube stats are low, but as you kill enemies and find extra swords and hearts in a level, your cubes’ stats grow. However, once you exit and start the next level, all your cubes’ well-earned stats reset back to their starting levels, as you don’t carry any extra swords or stats over to the next level. That’s the strangest set-up for an RPG I’ve ever played. Normally in RPG gameplay, all of your armour and stats do not disappear when you move to a new area.

Cube Decider fifty levels are set in the same environment with little to differentiate the levels from each other. The enemies, cards and collectables are easy enough to spot as you can spin the camera around. The maze walls also disappear if your cube walks too close to them, which I liked, meant I could see my cube at all times. It is not a difficult game to play unless the cube dies a lot, which can be frustrating when it happens. Graphically the game is fine, it is not going to blow you away with its glossy looks, but it gets the job done. In addition, a chirpy tune is a soundtrack to your cubes’ adventure; unfortunately, the music gets repetitive after a while.
Levels
Sound effects of metal swords clashing when you fight are a nice addition. While I played through the fifty levels of Cube Decider, I did enjoy the game for a while. It is not the worse game out there, but on the other hand, it is not the best game either. However, for a couple of pounds in the eShop, I’d still be hesitant to recommend it as it left me with a feeling off…. well, that it was kind of pointless after finishing it. You are a Cube with a sword; your default stats values are 1 damage point, 5 health points and 0 armor points. Borderlands: The Pre-Sequel Switch NSP

Your stats reset to the default values at the beginning of each game level. Then while you are making the way through the level, stats are changed depending on taken power-ups and defeated enemies. You initiate all attacks and decide whom to attack first. The fight is turn based. After you attack an enemy, the enemy will attack in turn if it is still alive. You can “die” if your health becomes below zero; but you can make successful attack even having zero health points. If you die, you will have to start the level from the beginning. Also you can restart the current level any time.
Visuals
You task is to attack enemies in the right order to have enough health, damage, and armor to be able to make it through the level to the exit point. Cube Decider is a logic puzzle game with RPG elements where you need to make your way through each level collecting power-up and deciding whom and when to attack using your logic and arithmetic skills. You’ll collect power-ups, upgrade your stats, and decide whom and when to attack in the maze. Boreal Tenebrae Switch NSP
