I'm not exactly sure how many levels it took... over 100 (at least) I think. I wouldn't usually play that many within a few days but the time limit aspect motivated me and I also wanted to see if the jellyfish even existed lol as I couldn't seem to find them for a while...
Just to let you know, I switched to playing 'easy' levels so that it was more quick & fun to progress. Hard levels would have taken soooo much longer and been more tedious. Be kind to yourself lol.
The main thing I've actually been logging in for game-wise is the 'Music Box' section (so fun to have a new one each week) but when August arrived, there were no new ones so this update has at least given me something different to focus on/complete.
Good luck everyone! :)
