Don't know what the expectations were, but Tearaway: Unfolded only got to No.33 in the UK charts on the week of release and promptly disappeared:

The article claims it's a flop based on chart position (a meaningless relative metric) and then proceeds to place it exactly between titles that I don't think anyone would be surprised to see it placed.
For a port of a handheld game it doesn't seem to be doing anything other than what I would guess it would have done; are people expecting Super Mario figures or something? What was success meant to look like for a port like this if not exactly what happened to it?
