Well, completed one of the modes anyway. The main mode, Arcade, seems to be just a score attack and as a result, can’t be completed. However, there’s a pretty large (70 level!) mode called Nostalgia, which certainly is completable. I know this, because I did it.
Unlike Arcade mode, Nostalgia Mode in Pix the Cat is more a set of puzzle and reaction based challenges. In each level, presented in awesome black and white old-timey animation visuals, you have to collect a number of eggs without trapping yourself in a corner or hitting spikes or a baddie. Sometimes you have 90+ chicks all following you, so route planning is important!
There are a few gimmicks to help or hinder you – owls that collect up then spit out your chicks essentially resetting your tail, mushrooms that reverse your chain so you’re warped to the back, and so on. Some levels have multiple cats, adding to the confusion. It’s a lot of fun, and I actually prefer it to Arcade Mode.
After struggling with a level around the 50-odd mark for aaaaaages, I managed to beat it today, and then went on to complete the rest of the 70 missions. Woo! I’d recommend Pix the Cat just for this one mode, actually. It’s the best of all of them.
Oh, and here’s a video of me finishing the impossible level (at the start) then mopping up the rest:
