Baseline (Widescreen) Solution & Issues
Resolutions are detected in-game. Only supports 16:9 (listed as "Widescreen"), 16:10, 5:4, and 4:3 ("Normal") aspect ratios. 16:10, 5:4, and 4:3 aspect ratios are letterboxed.
Any other aspect ratios have a stretched output for both platforming and overhead levels.
