Thanks so much!
ed. v3.0.2 hot fixes the level layout to stop you escaping; stopping you getting trapped in an appearing block at all will take a little longer to fix.
Yes- I see exactly what you mean about the blocks. I think you can only escape the bounds of the game on the first level; but it’s definitely a bug to fix everywhere. Thanks for reporting, I’ll take a look.
p.s. I’ve got the walkthrough videos up now, in the game description.
