[quote name='pROvIs']Played the first few worlds over my lunch break. Overall, I am very pleased with the game. The achievements seem a bit insane in some parts, ie 100 puzzles in a row without mistake. It encourages you to solve them so fast that I accidentally clicked the wrong number on one and screwed up my streak. I hope it keeps track over multiple times playing.[/QUOTE]
For me, that achievement makes me much more wary in inputting an answer rather than rushing through it since there's no timer involved in it. If you mess up, it just resets the progress, so you have ample opportunity to get it. I messed mines up the first time the Even/Odd cages showed up because I didn't read the instruction properly. You can actually replay puzzles to rack up the streak from what I've seen.
