Testing a first-person dungeon crawler with retro vibes (Heretic / Hexxen)
All combat is turn-based, allowing the player time to select their responses in combat (change weapon for instance)
The player can turn at 90-degree angles (this does not consume a turn) and moves cell by cell in the cardinal directions, North, East, South, West.
As for the screen resolution, it's 360x480 which gives a taller, more "portrait-like" aspect. This could evoke the feel of old handheld devices or cellphones. However, a square 360x360 resolution might fit better with the classic dungeon crawler layout, to emphasize symmetry in the grid-based movement. A square aspect ratio could also make it easier to display additional HUD elements without feeling cramped.
