That's a good guess, considering that I assume the DSI was the first hand-held console with a camera built in so I wouldn't be surprised if Nintendo wanted to make games that use the camera, good examples would be Photo Dojo and Face Pilot. So I agree, for being a small game you can tell they weren't really confident with the idea and sadly it didn't do well and almost nobody talks about it.My best guess is Nintendo wanted to see if the DSi's cameras were viable as a control scheme but weren't too confident and so they tried it on this small scale game and well it didn't work out.
It's a shame really, I feel like it had potential.
Ah, thank you!! I will actually draw more of Wario in the future since I wanna practice drawing him! ^^Nice! Definitely would like to see you draw the big man more often.
