Free IAP Premium Piano Numbers ($3.99) — Lifetime

I always liked the idea of learning piano, but traditional music theory can feel hard to start with.

So I made Piano Numbers: a simple way to play songs by following numbers, letter notes, and highlighted keys step by step.

You can learn from scratch with ABC notes, Do Re Mi, and beginner-friendly songs.

I also added two sounds to make practice more fun:

Real piano sound.

Acoustic guitar sound.

If you want to play simple melodies without feeling lost in music theory, Piano Numbers might be a good place to start.

Free Premium Snake Color Unlock ($3.99) — Lifetime

I grew up playing classic snake and brick games, and later got into match-3. I was curious what would happen if I combined all three into one core gameplay loop.

I added a few special mechanics to spice things up:

Red blocks explode and chain nearby clears.

Yellow blocks blast through entire lines.

White magic head wipes out a chosen color across the board.

If you enjoy clever mechanics and satisfying chain reactions, Snake Color might surprise you.

I'm a solo developer, and I've noticed that some subreddits really don't care whether AI was used to make an app or game. As long as the app is good and not low-effort, people judge it by the final result.

But in some communities, or from some people, there's a lot of hostility toward AI.

I've been criticized enough that I actually started trying to make my game look less "AI-made." And honestly, I did put real effort into doing that. But after a while, I got tired of constantly chasing other people's expectations and prejudices.

So I changed my mindset.

I still use AI as part of my development process, and I'm not ashamed of it. Some people will hate it, some will downvote me, and that's fine. I don't really care anymore.

At the end of the day, I'm still the one building the game, making decisions, fixing bugs, and trying to create something players enjoy.

And honestly, since I stopped worrying so much about what some people think, I feel a lot more free as a game developer.

For me, a poorly made product is still a poorly made product, whether it was coded entirely by hand or built with AI assistance. Low effort is low effort.

On the other hand, if someone puts real care, time, and attention into their work, then a good product is a good product, regardless of whether they wrote every line themselves or used AI as a tool along the way.

I'm genuinely curious how other developers feel about this. What's your perspective on AI in game development?

One more thing: English is not my native language. I wrote this post in my own language first and then used AI to translate it into English, so some parts may sound a little unnatural. I hope you'll understand.

The opinions above are completely my own. AI helped with the translation, but the thoughts and experiences I'm sharing here are mine.

I want to share a small story.

A while ago, I posted my indie game on Reddit to get feedback.

Among many comments, there was one that really stayed with me. A blind player, from a country very far away from mine, asked if I could add VoiceOver support so they could play the game.

At that time, my game was still messy. A lot of things were unfinished, and I couldn’t add it right away.

But I didn’t forget that message.

Later, when the project became more stable, I thought about it again. My game is still very small. Maybe only a few hundred people play it regularly. Maybe that person is the only blind player who will ever play my game.

But somehow, that made it feel even more important.

So I added VoiceOver support.

A few hours after the update went live, around 5 AM where I live, I got a private message from that player. They told me they were happy that I had listened, and that they were able to complete the first stage of the game.

Honestly, that message made my day.

Even more surprisingly, that player later shared my game on AppleVis, a website for blind and visually impaired users. Before this, I had never even heard of AppleVis. I didn’t know there was such a dedicated community helping each other discover accessible apps and games.

Seeing my small game appear there was something I never expected.

As developers, we often look at numbers: downloads, reviews, revenue, retention.

But sometimes, one real player is enough to remind you why building things matters.

So I just want to say thank you to the blind and visually impaired gaming community. Thank you for your feedback, your patience, and for reminding me that accessibility is not just a feature. For some players, it is the difference between being able to play or being left out completely.

If you are making an app or a game, and you have a chance to add accessibility support, please consider it.

Someone out there may really need it.

P/s: I wrote this in my native language and used ChatGPT to help translate it into English. If something sounds a bit strange, that's probably why.

Thanks for understanding.

I’ve been spending the last few weeks slowly building a small offline RPG called OS Core Quest.

At the beginning, everything was rough.

The combat felt bad.

The UI was messy.

The enemies had no personality.

Even the art style kept changing because I couldn’t figure out what direction I wanted.

I kept thinking “I’ll just add more zones and more content,” but eventually I realized the real problem was depth, not size.

So instead of endlessly expanding the game, I started rebuilding smaller things:

1. ⁠Enemy attack patterns
2. ⁠Replay value (Roguelite RPG)
3. ⁠Hidden endings
4. ⁠Balancing male/female play-styles
5. ⁠Permanent progression systems
6. ⁠Cleaner chibi-style visuals
7. ⁠Making every zone feel different

A lot of players from Reddit have actually helped shape the game through feedback, which has been surprisingly motivating as a solo dev.

I’m still learning everything while making it — balancing, UI design, App Store stuff, art consistency, localization, all of it.
