Confusing mess of a game with a terrible UI & butt ugly graphics. The whole thing is aesthetically hideous & unpleasant to navigate. Just a negative experience overall.

First impressions of this game are that it's a slower, much more obtuse version of Plants vs. Zombies with a borderline unusable user interface... and you know what they say about first impressions.

ProtoGalaxy — это атмосферная стратегия с элементами управления галактикой. Глубокая система развития цивилизаций, исследование звёзд и баланс ресурсов делают игру увлекательной. Прекрасная графика и оригинальная музыка добавляют погружения. Однако сложная система управления и отсутствие подсказок могут отпугнуть новичков. Рекомендую для любителей стратегий с элементами науки.
