The venue is amazing and the game flow is bang on.

Not because of the theme, more that the height of the game elements and the puzzle complexity would lead to very bored children very quickly.

Apart from the cold start, no.

The colour vision puzzle had a mechanic that displayed colours selected. There are steps up to the venue, and narrow doorways with ledges to step over. - definitely not wheelchair accessible. But easy enough for anyone ambulatory. I reckon they’d pop a stool in if you asked them.
