Incline ～Railway of devils valley～

The challenge posed by an unprecedented battle system.
This is the ultimate masochistic action game!

An "unarmed" hero who was been robbed of weapons. He uses freely the inclined railway through the village to fight against the devils.

The only way to defeat the devils is seal them up!

The hero is an devil slayer who has been robbed of his weapons.
He has no direct means of attack, and the only way he can defeat the devils is lure them into the sacred boundary at top floor of village and seal them!

Put devils on the inclined railway,
and transport them to the sacred boundary at top floor of village!

To transport the devils to the sacred boundary, use the inclined railway that through the center of the village.
Load up arbitrary number of devils in the cargo bed of an incline railway and off you go!

The more devils, higher the risk.
Dodge the fierce attacks of the devils!

You must keep dodging enemy attacks until you reach the top floor of the village.
The more devils you put on the cargo bed, the higher the risk, but the greater the return on a successful seal.

Seal the devils and earn the souls!

Once the cargo bed with the devils on it reaches the top floor, run for the "altar" behind the sacred boundary!
When the pursuing devils enter the sacred boundary, by sealing, you can round up all the devils.
If you seal them up, you can earn a lot of the "souls" they have accumulated.

High risk is high return, low risk is low return.

The amount of souls you can earn depends on the "number" and "color" of the devils you sealed at that time.
Higher the number of devils, and higher the percentage that matches the "Auspicious colors", the higher the score (souls).

Earn souls, rescue the villagers, and explore.

The souls earned are needed, to restore the "someone whose soul has been drained" to sanity.
By helping them, you will expand the scope of your activities in the village.
Souls are also extremely useful when traversing the cave areas that spread throughout the mountains.
Earn many souls and explore the romantic "Japanese world" of the late Meiji period to the fullest!

A battle system that allows you to experience
the joy of improvement through repeated trial and error.

The hero of this work is an unarmed devil slayer who has been robbed of his weapons.
Therefore, in this game, there is no "getting stronger by acquiring new weapons," as is often the case in other games.
In other words, in this battle system, it is purely only the player's own "training of skills" is the thing.

Sounds difficult? But don't worry.
The key to this game is combat using an inclined railway, but the number and type of devils loaded onto the cargo bed is up to the player. While you're still getting used to it, keep the number of devils in the cargo bed to a minimum, and as you get better, increase the number and variety. The greatest feature of this inclined railway battle is that you can adjust it to suit your own abilities and preferences!
Through repeated attempts, I hope you'll experience the joy of gradually improving.

You can also enjoy Co-op Battle!

The work has a "mode selection function" that allows the user to enjoy two modes.

[Adventure alone]:
In this mode, the player explores the village while fighting devils by using the inclined railway.
There are two different endings.

[Co-op Battle]:
A mode in which only the battles on the inclined railway are played repeatedly.
Aim for a high score with breathtaking co-op play.

Platforms	・PC (Steam) 　・Other platforms will also be supported.
