Welcome
To celebrate the launch of Horror Game Kit 1.5, we’re bringing you a new type of challenge! We’re providing detailed theme settings to help you enhance your game development skills by incorporating popular elements in horror game design.
Plus, you'll learn to promote your game by completing a video creation task.
Theme
Doors
In this game jam, participants will delve into the ominous theme of Doors, exploring their symbolic and literal meanings in horror. Each door can hide a mystery, lead to salvation, or unleash terror. The player might navigate an endless hallway of identical doors, unlock forbidden chambers, or decide whether to open a door that emanates unsettling sounds. The tension lies in not knowing what lies behind each threshold—and the consequences of finding out.
Please note: The content provided in this background is intended to help jammers understand the theme. You are free to interpret and develop the theme as you wish. The final game does not need to strictly follow the background story.
Key Features:
- The Unknown Behind Doors: Build suspense by making players decide whether to open doors, knowing danger might lurk behind each one.
- Story Background: Please create your own storyline that fits the theme.
- Exploration and Choices: Allow players to uncover secrets, solve puzzles, or escape a labyrinth of interconnected doors.
- Atmosphere of Fear: Use creaking hinges, shadowy outlines, or unexpected events to make each door a nerve-wracking decision.
Hints:
1. Play with the concept of “locked” and “unlocked” doors—what does it mean when something was left open?
2. Experiment with non-linear gameplay, where doors lead to vastly different places or realities.
3. Add escalating tension by making some doors one-way exits or time-limited opportunities.
Special Task
1. We have prepared a tutorial on how to replace Lever Puzzle, and now we invite you to try replacing it in your own game!
2. Take a screenshot or record a video of the Lever Puzzle in your game and put it on your game itch submission page.
3. We will give you additonal 10 points to your game if you do 1&2!
4. Looking forward to seeing your puzzle!

The Rising Star Award is designed to help and motivate game creators to increase the attention of their games and promote the feedback and communication among game enthusiasts.
The awarding rule is that if the number of downloads exceeds 100, we will give an additional reward corresponding to 10% of the number of downloads. Each 100 downloads is counted as a level interval. For example, if the number of downloads reaches 100, we will offer a reward of 10USD$; If it reaches 200, we will offer a reward of 20USD$. The upper limit of the bonus is 50USD$. We will conduct data statistics according to the download data within 7 days after the end of each Game jam.
Based on our experience, we suggest that everyone carry out more game promotion activities outside the website and carefully decorate their own game pages.
Some tips for increasing the number of downloads：
1. Detailed game introductions
2. A more exquisite display page
3. High-quality video presentation
4. Actively spread on various major social networking platforms
NOTE: We encourage everyone to share the game with external groups. But to ensure the fairness of award distribution, we will check the authenticity of the download data. We reserve the final right of interpretation for this activity.
