This app gets you a ridiculous amount of diamonds.I hope the fun of making things reaches everyonewho can laugh at something silly with me.
For a long time I could not go to school.It was a hard, hellish stretch of time.But then I found how fun it is to make things,and I took one step forward.

“Infinite diamonds in Minecraft, from my own addon!”It started from that silly dream.

Every bit of pocket money has gone into building this. Anything you give goes straight back into running and developing it.

Before You Download

  • We are reachable.Questions, feedback, or support — email us at cubicenginestudio@icloud.com and a real person will answer.
  • Your recordings never leave your PC.CMCUBE processes camera, microphone and screen capture entirely on your own machine. Recordings are written only to your Videos folder — never to our servers.
  • We never collect a child’s name or email.Branch World needs no sign-up. Progress and the cards you lay out stay on your own device. No ads, no analytics.
  • Windows may warn you.You may see an “unknown publisher” or Smart App Control warning. That is because we have not obtained a code signing certificate yet, not because anything is wrong with the file.
  • What you make is yours.Videos exported from CMCUBE are royalty-free — monetize them or use them commercially, freely.

Work With Us

We take on client work, built on the same skills behind our own products. We handle everything from planning to release and maintenance.

Mobile apps

Apps for iPhone and Android. We have five apps live on the App Store, including tinyCUBE, CUBICENGINE and Branch World, so we can handle the review process for you. Two of them, including Konokokinoko, are also on Google Play.

Windows desktop apps

Screen recording, audio processing, video export — things a browser cannot do. We built all of this in our recording tool CMCUBE.

Websites & web apps

Mobile-ready, search-friendly sites. Branch World and Mpack IDE run right in the browser, and we built both ourselves. We stay on for updates after launch.

Booking & ordering systems

Take bookings or orders online, stored in a database and visible from a dashboard. We built and ran one for our own lunch box shop.

Payments

Any of the above can take payments. We run card payments (Stripe), PayPal and App Store in-app purchases in our own products.
