Hold up, checkpoints are out now, yes, or just for those with early access capabilities?
Just realized I didn't look at the non-demo version
Latest version should be 0.0.3a, and it should have functional checkpoints, but let me know if for some reason they aren't working!
Ah no, it was I had the demo version and didn't know the 'full' version was out, I'll test here in a minute.
