Click on the little purple square box and drag it to the next checkpoint or this is how you create the next checkpoint

As you see in the video I tried that and it didn't work. What's more is what happens if I delete all my checkpoints?

Ok, now it's drawing lines but only from the one checkpoint and none of the others and even when I do draw it, it won't create a new checkpoint nor will the line connect with any other checkpoints.

I've had this problem as well, checkpoints don't work for some reason. And the game will crash for just switching between shaders and background tiles (after placing them).

Graphics are bugged for me too, I can't select them after I place them, I have to reopen the map.

Can you publish that map and share a link, so we can look into it?

Scratch that, we already figured it out, we'll update next week.

Any chance I can get a pacific day so I know when I can get back to working on levels?
