I've uploaded a beta on Steam that supports LiveSplit auto splitting using the ASL script I put in the resources section. To access the beta right click "Super Bernie World" in your Steam games library, then open Properties, then the Betas tab, and enter the code "speedrunstrats" to unlock the beta. Opt into the beta at the top of the tab then close the window. You might have to "verify integrity of game files" in order to force it to update.
Once I get confirmation that everything is working as expected from users on all three OSes (Windows, Mac, and Linux) I can make this build public to everyone and upload DRM free versions to itch.
Enjoy!
EDIT: Oh yeah the new version also lets you change music and SFX volume independently so you can play different music while still getting sound effects.
Still looking to hear if everything works well from people on different OSes, especially Mac/Linux.
Also I'm considering redoing the auto splitter so that it splits at the very end of the level when it transitions, because the frame rule doesn't kick in until the bus arrives so splitting at the flag won't tell you if you've missed a frame rule until the next split. If I change it runners can immediately see if they've missed a frame rule in a level and reset.
Thoughts?
