Fiendish? No, it's downright malicious. Queens is a simple platformer that gleefully seeks to end your Queen's life at every turn. Imagine everything you found most punishing about an old-school platformer - the instant deaths, the sudden falling spikes - except delivered with perfect comic timing.
Queens is brutal yet deliberately and amusingly so. It's only a few screens long, but let me know if you manage to finish it.
Bizarrely enough, it was created for entry in an indie design competition themed around domestic violence. It'll make sense once you play it.
