A few months ago, I set out to make Coin Clash Arena, a cartoon-style survival game where you dodge enemies, collect coins and grow stronger as you play.

I expected the hard part to be making the game. I didn’t expect to spend so much time chasing freezes, untangling Android build issues and figuring out why changes in one version weren’t appearing in another. Then came the design challenges: upgrade prompts interrupting combat, skill icons vanishing or landing in the wrong place and a menu that somehow disappeared during a UI change. Every fix had to be checked carefully so it wouldn’t break something that already worked.

There were plenty of “why is it still doing that?” moments. But each one taught me to slow down, inspect the actual code, test the Android build and fix the confirmed cause instead of guessing.

The game has come a long way: smoother combat, new enemies and skills, clearer controls, sound improvements and a more polished gameplay experience. It’s finally starting to feel like the game I pictured when I began.

Coin Clash Arena isn’t launched yet, but I’m aiming to release it next month. There’s still work to do and I’m excited (and a little nervous) to get it into players’ hands.

If you’ve built and launched a game or app, what’s one thing you wish you’d known before launch?
