The last achievement I needed was "150 clicks". I ended up replaying a map where there were a lot of + click balls because I'm a junkie. I need AA (Achievements Anonymous).
I thought the last level was awesome. People whining that it wasn't a puzzle are right that it's not a puzzle - the puzzles could only get so complicated with this setup, so the final level relies on SKILL instead of puzzle solving.
This is the same puzzle that I used to get frustrated with on Super Nintendo games like Final Fantasy III and Super Mario RPG. It was boring then, it's boring now.
You know what, robot, I got you a kitty, I got you a puppy, I've helped you chase after a fishy for twenty minutes. You can go without fishy unless I have badges to chase after (which I surely will soon.)
