Reliable Game Development Partner That Delivered What They Promised

Yousef Al Mansoori / Founder & CEO | Oct 11, 2026

Overall we had a good experience working with iFenDuo. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The Game Development work has already made a noticeable difference — tasks that used to take hours now take minutes. A couple of milestones slipped by a week or so, mostly around testing.

Happy to recommend them.

Project summary

iFenDuo was brought in to develop a casual mobile game from concept to launch. The work covered requirements, design, development, testing and launch support. The engagement ran for about 4 months.

We were very happy with how this project went. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.
