      Testimonials

      Мы заказывали у KISS Software анимацию для 2D-платформера. Ребята сразу поняли нашу стилистику, предложили интересные решения по эмоциям персонажей, а результат превзошёл ожидания. Игроки отмечают именно «живость» анимации. Будем работать ещё.

      гейм-дизайнер
      Нужно было подключить аутсорс на этапе риггинга и внутриигровых синематиков под Unreal Engine. KISS вошли в проект аккуратно, без долгих вводных, всё отдали в срок, багов — ноль. Отличная техничка, быстрая реакция и понимание продакшн-процесса.

      Уже третий проект делаем с командой KISS — всегда всё прозрачно, по делу и вовремя. У них реально хорошее чувство гейм-драмы и движущейся композиции. Отдельно ценим их подход к оптимизации под мобильные платформы.
