[p]No new content until Next Fest, but I wanted to upload this build early because it does huge things in terms of opfirmization. I'd be interested in hearing feedback on this, particular for those who had trouble running the game or experienced significant lag.[/p][p][/p]

• [p]Optimized GPU usage, reducing its performance cost by over 4x![/p]

• [p]If you adjust the Starting Layer slider without resetting the mine, you are not prompted when starting a new day.[/p]
