General Idea

Isometric 2.5d roguelike focused on a Boss Battle
-two rooms - a spawn room in which the player can practice skills and one in which the Boss Battle happens
-Norse themed
-Ice everywhere
-Camera is fixed

Art Style

Pixelly 2D art
-do regular shady art style, then pixelate and refine in photoshop

Boss Behaviour

-Boss does different things at different points of the battle, and a different approach can be taken for each of their behavious to get a leg up
-look at Shadow of the Colossus, Cuphead, and Monster Hunter for inspiration
-don't show health bar of boss

1st Stage

Blocking / Retaliation
In this stage, the boss walks toward you slowly. If it gets close to you, it attacks. Whenever it gets hit in this mode, it backlashes everything in a circular range with a set amount of damage.
Beat this stage by hanging back and using ranged attacks outside the range of its retaliation.

2nd Stage

Evasion / Ranged Attacks
In this stage, the boss circles around the edges and shoots icy projectiles at you, with timed cooldowns in between. If they hit you you take some damage and are frozen for a second.
Beat this stage by holding up shield and deflecting at the right time.

3rd Stage

Agressive Melee Attacks
In this stage, the boss runs toward you and attacks melee without shielding. After each attack, it takes a couple of seconds to cool down.
Beat this stage by blocking, stunning, then meleeing.

4th Stage

Charging toward
In this stage, the boss circles around the edges, then charges at you with a cooldown between. It then immediately shields.
Beat this stage by standing next to columns when the beast charges toward you, then dodge at the last second to force it to hit. the column, which stuns it.
