I bought this from Gamestop ($20.USD) berfore I was able to DL it... Google it.. you'll find it.... BTW it is the identical same version as the Download-able version of the same on the 3ds. Game stop = $20 USD, eshop = $8.00 USD...Which makes me wonder as titles like system flaw for the DSi were wittled down versions, not full ones (containing 100 levels on retail version of system flaw...)
Heck HOUSE MD was $30 USD retail but sold for $8.00 USD an episode on eshop, making it higher for digital version...
I would have bought it anyway but I would have waited for a price drop first.... At least this way I can play it on all 3; DSi, XL, & 3ds..
Although the graphics are sub par, the game play is fun, though a bit on the easy side (at least early on in the game...) The four tiki gods, main quest, is a bit short though, 10 levels each quickly played through but the daily makes up for it, have not gotten to iron frog (hard levels?) yet though..
On these games I like the daily play part... I have a whole host of puzzles I play eery AM with coffee to get the grey matter movin'...
