One sensible gauge of a platform's importance in a market is the volume of developers willing to create and release games for it.
Once that platform begins tempting previously committed developers away from rival formats, well, the game is almost up.
French studio ODenis was responsible for the Nintendo DSi game Pop Island, a cutesy capture the flag title available from the DSi Shop.
'Was' being the operative word - or rather operative tense - for ODenis is branching out to iPhone game development through Rising Board.
A wakeboard simulation set within the Pop Island universe, Rising Board involves your tilting the iPhone to manoeuvre the penguin surfer from left to right.
If you fancy a ride on the surf, download it now for 99c. And if you're still on the fence, check out the video below.
