Heyo, Just a small update to fix a few things: - Fixed an issue where level saves would disappear if you started the simulation. (thanks for the report!) - Fixed certain hotkeys not working on alternative keyboard layouts such as AZERTY. (thanks for the report!) - You can now also use ctrl+shift+z to redo for those of you who prefer it. (thanks for the suggestion!) Additionally, I forgot to publish the new achievements for the 3 new levels yesterday, so they should now be working. (thanks for reminding me!) Cheers!
