Here is the version 1.08 from Flux Caves and it contains some bigger changes! 

• First of all, the Linux support is live again!
• Also I made a main menu, where you can turn off  Volumetric Lights which will help for some Linux player, and without it you can earn some extra FPS
• Optimized almost all the levels, and the 'OpenWorld' too. This means about 5-30 extra frame per second

Also here is the first screenshot of the first free DLC. Which will contain 10 extra levels
