How to get: OWENII, MANTELLI, AUSTRALIS, ROWI, HAASTII ??? I see no clues or hints of a solution. focus on music?

This game generates a Windows pop-up that requests my username and password. Every. Single. Level. What gives? I know this thread will be ignored like the others. Oh well. EDIT: It also pops when I unlock an achievement, it seems. I've taken a screenshot. It's not in English, but should be understandable. It's really annoying. https://imgur.com/FzHisrZ...

is there undo in the game?

Found a couple minor bugs. ^^; 1) Minor bug: Levels temporarily re-locking on level select - Levels locked on the level select for the most recent World can also become locked on previous Worlds. This happens if you look at the World with locked level...

I cleared all 20 stages from what I assume is world 1 ("The Forest"), but I didn't get the achievement for completing world 1. Am I missing something? Are there more levels in world 1 that I have to unlock first? Or do I have to do something special to "complete" a world? Or is it a bug? Cheers ~...
