Cally's Caves 2

It's time for Cally to do what she does best: rescuing her kidnapped parents!

Set before the events of Cally's Caves 3, Cally's Trials is a roguelike action-platformer with a weapon-levelling system that lets you evolve weapons as you use them. Cally must save her parents from the maniacal Herbert, who has laid waste to the Caves and built a massive lair deep inside.
Herbert's experiments have twisted the caves into a living nightmare, and our plucky six-year-old heroine must overcome staggering odds:

* 110 levels packed with vile monsters to fight across 6 biomes * 6 insane bosses, including Mama Bear's first appearance, and Carl IV's Dad. * 12 weapon classes to level up, use your weapons and they grow stronger, every once in a while they evolve into a new form with new effects! * Item/Powerup Store to buy permanent upgrades for Cally * 38 song soundtrack * roguelike structure means earning money on every run and buying upgrades is crucial to success

Cally's Trials is a mix of roguelike and RPG, with a "Level Up Everything" sensibility. Witness the beginning of Cally's journey from average 6-year-old girl, to fearless warrior and Conqueror of the Caves!
