2D, 2.5D or 3D? Titan Soul

Game Play & Game Design

Hello guys.

I’m played the demo of Tital Soul on Steam and I have a doubt about the game graphics.

Titan Soul is a 2D tiled-based game, but the boss fight confuses my mind:

The boss stuff is 2D, 2.5D or 3D?

Here some file I found in the installed folder: http://s1.postimg.org/ic2f7cotb/eyecube.png

This is similiar to other game called YS:Origin, the game is 2.5D with 3D boss effect.

Looks like 2.5D due to the way they rotate the sprite abruptly

I was watching this video the other day:

and apparently (this was streamed live on twitch) the devs were in the chat. They confirmed that the bosses (maybe not all of them) are in fact 3D.

This game looks 2D. Not even isometric.

EDIT:
Incase you don’t know the definition of 3D, it’s basically the ability to look at an object from bottom, top, and all sides. This game does not show any bottom.

I say it isn’t isometric because the tile layout is perpendicular to the window, isometric graphics (and I might be wrong on this) are usually tiled at 45º angles in the window.
