Sonic: Hellfire Saga

This is a hack of Sonic 3 & Knuckles that is a cross-over between Castlevania, Ghosts 'n Goblins and Sonic game series, focused on boss fights (but not forgetting fast-paced platforming either!) and providing a unique story and aesthetic not seen in other hacks of the Sonic games.

Overall features:

* 10 acts of fast-paced platforming and hard-as-nails fights across 4 zones;

* 15 mini-bosses to fight, 3 major bosses to really sink your teeth into, and one final boss that really is something special;

* A soundtrack of remixes and original songs that pushes the console to its absolute limits, available in the Sound Test as well;

* Four difficulty modes, including Normal, Hard, Assist (if you're struggling, and we don't judge by the way!), and Maniac (if you are truly insane);

* And finally, a mode that disables flashing effects, if you need that.
