Not only are my achievements gone (like everyone else, I assume this came with the Blocks rollout), but the feedback page doesn't give me the option to attach images or even add text when I select that it's the achievement for the BotD that's missing. Good thing I never use the chat and will get no use from stickers...
I had an abrupt, negative change of opinion when level 14 was more of a skill level than a puzzle level.
Level 18 felt a little grind-y, especially as I waited for the last two blocks to be the ones that randomly flashed.
And I agree with those noting it felt like too many "trace your path" levels.
Otherwise, an enjoyable game!
