I'm Taking Part in the Defold Game Jam

Hello, this is Yuu! Last week I posted my look back on the js13kGames feedback, but without ever announcing it on the blog, I had actually entered Defold Game Jam 2026, which ran right after js13kGames. Two days left until the deadline. Today is the real crunch, so with time this tight, I’m keeping this post short. This is my first time using the game engine Defold. I had started building a game in Love2D after js13kGames, and since both are built around Lua, I went in expecting to have no trouble with it. I had only worked through a few tutorials before the jam started, so there was plenty I didn’t understand at that point, but by now I’ve gotten fairly comfortable with it. I had never used integrated environments like Unity or Godot before, so this kind of editor isn’t my strong suit, and yet it turned out to fit me reasonably well.

Taking on the Online Category

Hello, this is Yuu! I finished my js13kgames entry last week, and while I personally think it turned out quite well, the number of entries in the general category has grown rapidly since then. There are already 63 submitted entries, and if we include unfinished ones, there are well over 100 entries in total. In contrast, there were only four entries in the online category last week, and there are still only five as of the time of writing this post.

Unicorns and Rainbows

Hello, this is Yuu! This week, I started making a game for js13kGames, which started recently. Rather than only sharing my development progress on this blog, I’d also like to participate in game jams like this in the future. This year’s theme is “Unicorns and Rainbows.” It’s not a theme that I’m particularly familiar with in Japan, but personally, it reminded me of the time when MLP (My Little Pony) and bronies were popular.

Always Chasing Hanafuda Refactoring

Hello, this is Yuu! There hasn’t been any major progress since last week. I’ve mostly been working on the lobby screen, which had been nothing more than a placeholder screen until now. I’ve also been repeatedly refactoring the code because it keeps getting bigger and bigger. At this point, I sometimes start to wonder, “What am I even doing?” This is something I’ve struggled with since the Flyjong days. I tend to enjoy making games starting from the code rather than writing code based on the game I want to make, so this kind of situation can be surprisingly difficult for me.

Even Hanafuda Turned Into a Rabbit Hole

Hello, this is Yuu! Last week, I lost a bit of motivation while working on the game’s UI. To take a break, I spent some time building a small web app and even experimented with a shooting game. In the end, neither project felt substantial enough to share, so I ended up taking a short break instead. Interestingly, stepping away from the project had the opposite effect I expected. After the break, I found myself motivated to work on the Hanafuda game again.

About the Concept Behind My Hanafuda Game

Hello, this is Yuu! This week was mostly about polishing rather than implementing new features. I spent most of my time fine-tuning things like how the cards move and how they feel when placed on the table. Choosing to make the game in 3D seemed like a casual decision at first, but I’ve started to regret it a little. Before I knew it, another week had passed just adjusting the UI.

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

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

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.
