The working process

Project development is always a difficult task. There are pitfalls, difficulties with forecasting terms.

We corrected

  • Authorization

    Authorization through social networks (Vkontakte and Facebook).

  • Interface improvements

    No information windows for erroneous server responses (No internet, Server error, etc.). For example, if the server did not respond during authorization, then the application would freeze and the user would not receive feedback about what caused the error.

  • General bugs

    Freezes on game levels, lagging sound and audio elements, problems with Wi-Fi connection, processing of server logic.

One of the common mistakes of studios is the lack of specialized QA testing due to the lack of a professional employee in the staff. Often, programmers or project managers are involved in checking the work, which entails an unfinished and “raw” product.


What difficulties did you encounter while implementing the project?

The current client-server logic did not fit the customer's tasks and was completely rewritten for C# (ASP.NET).

Were there any pitfalls during development?

Refining a project is always accompanied by pitfalls. We were lucky that the previous team commented on the code and we figured out all the nuances pretty quickly.

Customer feedback

We are certainly flattered when the customer is satisfied with the results of cooperation. This means that we were able to bring his ideas to life:

“Of course, I am satisfied with the result of the work. Not everything is perfect, but given that this is my second experience with the studio, Crocoapps.com fully met all my expectations»
