I've Started Making a Hanafuda Game

I've Started Making a Hanafuda Game

Hello, this is Yuu! After last week’s release, I’ve already started working on my next project: a Hanafuda game. This time, I’m also challenging myself to make it in 3D. Just like Flyjong, I’m building everything without using Unity or Unreal Engine 5, and so far the development has been going smoothly without any major issues. I’m very happy with how my previous game turned out, but it also took much longer to release than I had originally planned. This time I’d like to finish the project in a shorter amount of time. That said, I’m experimenting with several new ideas, so it could still end up taking longer than expected. I also plan to add PvP, so I’ll probably keep the visual effects a bit more restrained and focus more on the gameplay itself.

Working on Mahjong Tile Design

Working on Mahjong Tile Design

Hello, this is Yuu! Following up from last week, I’d like to share another update on my Mahjong game project. Right now, development has progressed to just before the AI implementation stage, and I’ve been focusing heavily on the UI. One thing I spent a surprising amount of time on this week was the appearance of the Mahjong tiles. I actually ended up redrawing them three times.

Developing a Mahjong Game Has Been Tough

Developing a Mahjong Game Has Been Tough

Hello, this is Yuu! Ever since I suddenly decided that I wanted to make a Mahjong game, I’ve still been continuously working on it. Right now, I’ve finished implementing calls such as Ron and Riichi, and I’m currently working on hand evaluation and score calculation. As for the progress since my last post, the complexity of the game has made me play Mahjong constantly just for reference and testing.

I Started Making a Mahjong Game

I Started Making a Mahjong Game

Hello, this is Yuu! It has already been about two months since my roguelike Sokoban project stalled due to asset-related issues. I still want to come back to it someday when the timing feels right. Recently, I came across a Mahjong game that reminded me of an old title I used to play many years ago. The nostalgia hit me harder than expected, and before I knew it, I had spent the entire night playing it.

Two Weeks Since Starting a New Project

Two Weeks Since Starting a New Project

Hello, this is Yuu! It’s been about two weeks since I started working on a new game after releasing Dicewar. This time, I’m developing a puzzle-focused game that combines Sokoban-style mechanics with roguelike elements. I initially thought it would be something I could build casually, but the goal is still far from clear, and it’s turning out to be more challenging than expected. The screenshot shows a test map I’m currently using, and as you can see, the in-game visuals are still represented with simple symbols.
