Rift Lords is an old style, pixely, sidescroller, adventure, rpg. It is currently compatible with the Darkplaces and FTE engines.
Rift Lords is still in early alpha stages.
The story takes places in a medieval time where Cid, our adventurer, runs into issues with his mad alchemist friend who accidentially tears rifts though time and space. Cid, being young and spry, is left to deal with the situation, but among his tools includes the ability to craft spells in nearly unlimited ways. Choose an element, then choose how the spell will react when it hits an object. This can build up to some pretty intense combos.
