I finally finished the split screen co-op I was testing during the Steam Next Fest - you can now play with up to 4 players on the same computer (or remotely with Steam Remote Play)! You can watch the dev stream where I tested co-op for basically the first time here: [previewyoutube=Ub7gLms3akw;full][/previewyoutube] This update also includes a lot of improvements and fixes based on feedback we received during the Next Fest! I hope you enjoy, and definitely let me know if you have more feedback! Changelog:

• Added split screen co-op
• Splitters will now rotate to redirect items to factories directly from rigs/producers
• Assembler can now queue multiple of the same item
• Now shows how many remaining items needed for structure while building
• Added notifications and reminders if you cannot do something
• Now shows power cost and size (4x4x3 etc) in structure hover info
• Smoothed out jumps - they now increase height if you hold jump key longer
• Added invert y axis option
• Minor improvements and bugfixes
• I might have added a secret area to the game (new saves only)
