It is a fun game but unfortunatelly has multiple bags and pretty often you have to start level from beging just because game gives you critical error. Game doesnt even start with direct 10/11, I had to use direct 9. I think this game need a big patch note before it will be actually playable on satisfactory level.
Game itself is not hard and generally you just have to collect cristalls and find tower to finish level. My negative review is based only on all those critical errors I got during my play time.
