Downhill Battle

Downhill Battle is a mystery RPG Maker VX Ace game, with elements of horror. There are a few puzzles, but the focus is on the story. There's only a demo so far, but I expect to have the whole game out sometime this year.

Frosty is the beloved cat of the Caine family, a good luck charm against a curse. A person chosen by the curse has their mind destroyed, and body rendered useless, culminating in death after a few years. There was only one anomaly-Norisuke, great-great-great-etc-grandfather to the current generation of Caines. He believed his first cat, Sol, saved him from a terrible fate. Now that your family is showing signs of the disease and dropping like flies, you hope to pull off the same miracle that Sol did, so long ago.
