The Programmer's Sale is running from the 3rd-10th October, and Hexahedra is part of it! It's a celebration of programming and engineering games, so Hexahedra will slot right in.
Hexahedra's demo is already out, and I'm planning to launch an update to add sound effects during the sale, so you'll be able to hear devices clanking, rumbling, and hissing their way to creating your cubes.
Optimization is an important part of programming, so I hope to see people breaking records for Hexahedra's demo puzzles!
