I bought it last saturday after looking for a copy for ages. Game in Leicester had 2 copies in the second hand section, priced £29.99 each. I decided to go for it, even though that's a lot of money but I really wanted it for my GC collection and I hadn't seen it for months.
I've got to say it was £30 well spent. I'm really enjoying it, and spent about 4 hours playing it yesterday. Obviously its really quirky but I love obscure Japanese games. Its definitely one of the best I've played

Oh, and some of the translation is intentionally laugh-out-loud funny, which I really like too.
Chibi himself is so full of character and charm its hard not to like the game. It really is a novel idea being 4 inches tall and having to scale massive heights and dangerous climbs just to reach a work surface!
Its also a very clever game in that it plays like a large selection of puzzles which can be done in your own time and in your own order. Each puzzle affects the subsequent one and the game quickly becomes layered and therefore very absorbing. Its cartoon images definitely masks a very deep game
I'd say if you can find and afford it then you won't be let down. I hope that helps
