Probably a bit of a long shot, but does anybody happen to know what the items in the shop do in the Mission Driller mode of Mr Driller Ace? The expensive items give you the option of having more than three lives, but I can't work out the other ones. There are 10 of them (numbered), and I've bought them all, but I can't see what they do. The FAQ on GameFAQs just says they're "Driller level 1-10", which doesn't really tell me much.
Anybody know what they do?
