Did you work in a team?
Creating this solo was a blast! To complement the low resolution theme, all of its sounds are built additively from sine wave components. This was also an entry for Brackeys Jam 2020.2, whose "rewind" theme inspired its time manipulation controls. Enjoy!

Was the resolution a challenge?
When I entered LOWREZJAM I had absolutely no idea how to go about the resolution requirement. For the text I made my own pixel font and exported the splash screen as two sprites. Initially I wanted the radial symmetry to be achieved with equilateral triangles (with the 64x64 viewport inscribed within a larger hexagon) but found that a 2x2 grid of 32px squares had less aliasing and was easier to work with.

What did you learn?
My engine is built for 2D audio spatialization. To achieve the z-index (i.e. time traversal) I made separate ceiling and floor layers and interpolated between them based on the z-value. For performance only two floors are audible at once. So effectively the observer is moving up and down through an infinite stack of 2D procedural sound stages that get instantiated and destroyed when needed. It's like riding an elevator.
