So, I just completed the "curiosity killed the mouse" level, took 3 people a while to realise what was going on, but after a few minutes we got to the non-obvious solution, and I got sent back to the first level. I feel a bit screwed over now... =|
Don't worry, it always comes right before the last level, so you didn't lose much.
Is that still true, Magnificent Cursors Creator? This morning, I finished it and, if I'm remembering my pre-coffee activities correctly, a few more stages after it and never reached the end.
It should be, unless there's a bug. But I'm pretty sure there isn't a bug...
