Guess Combination Lock Game - Cross Platform Beware hiring this group. A 6-week project took over 9 months! You will have to beg them to do the slightest bit of coding. Even with an offered additional bonus to complete on time, they didn't care. My project was a small $700 project, too small to get the attention from this group apparently. In the end they only want the money. Naively I was convinced to pay the final milestone before the project was complete. They already had me hostage at this point, so I felt maybe it would light a fire. It did not, their response and desire to complete the project became even worse than it was. I have a couple active projects right now with other freelancers, and several successful projects that have been completed on Upwork. Overall Upwork freelancers and companies have been great. Just not this one!
