What players say

97% of 6,250 reviews are positive · 97% of 73 in the last 30 days

Players praise the flexible solutions, machine-building, and depth of optimization. The most common complaint is that larger designs become tedious to edit and debug due to limited copy-paste, grouping, breakpoint, and reverse-step tools. Some players also find the campaign repetitive when they focus only on completing each puzzle.
