A downloadable game for Windows

It is recommended to play this game with a controller over a mouse/keyboard setup.


Hello! And thank you for testing A Koi Story! This is a project I’ve been working on for roughly six months. It's currently in a stable state, and I will continue to find ways to refine it as I grow my skills!

Step by step:

  1. Download the game’s zip.
  2. Unzip the game’s folder to your desired location, probably Documents or Desktop.  Keep the .exe and other files in the same folder.
  3. Go ahead and play my game!
    • Please take notes while you’re playing!  The game has a pause button so you can jot down thoughts and impressions as you play.
    • If you find a bug that breaks the game or you feel needs to be reported separate from the rest of your testing, please report the bug to me following these instructions.
  4. Once you’ve finished the playthrough/you’re done with your playthrough go to the Google Form I’ve created here: https://forms.gle/uqrjvrLW9T3qiMHT8
  5. Please take time to fill out all the questions. There are a lot, but your information is critical to development!

Optional. Check on the living document here to see if bugs you’ve found are already documented or being worked on!

Bug Reporting

  1. Please check the live document to see if it’s an existing bug that’s being worked on.
  2. If it’s a new bug you haven’t run into, or you feel it’s different from a similar existing bug, go to this form and fill out the information.
  3. Pat yourself on the back! Check in to see the bug get documented and worked on.


Jinlong, a 12 year old that wants a pet dragon, has decided to bring his pet fish up to a waterfall to see if it will turn into a dragon.  The mischevious water spirits in the forest do what they can to taunt and dissuade him.


This is a school project I've been working on for the last 6 months at the Academy of Interactive entertainment! A big part of the project is the path that winds up the mountain! The Path is generated at runtime before you start each time. I'm still working to refine it and hopefully eventually have it fully procedural!  Right now, you'll notice the foliage is always different, and the path winds differently each time.
One of the major improvements I'm looking to make 


There's no dedicated controls page, but currently the gamepad control scheme is shown on the pause menu.  The mouse and keyboard commands are:

  • WASD - Move
  • Left Mouse- Standard Attack
  • Center Mouse - Ranged Attack
  • Right Mouse - 360 Power attack

Character Stats & Combat

The character's stats are currently only sited in the Orb investment screen with little description (sorry!). A better UI for the Orb Investment screen is in the works.

  • Health- How much damage Jin can take before he must retreat home
  • Attack - How much damage jin can deal while attacking
    • Standard Attack - Base Power 60
    • Ranged Attack - Base power 30, stops and pushes enemies back a bit.
    • Wide Attack - Base Power 120, has a 2 second cooldown before it can be used again. (currently, no UI for cooldown)
  • Defense - How well Jin resists damage. 
  • Speed - How quickly Jin can move.

The damage formula is - (P *(A/D) * (L/100))

  • P-Attacker's attack power (ie, standard attack base power 60)
  • A-Attackers attack stat
  • D-Defender's defense stat
  • L-Attacker's level
