I'd imagine the only reason the game exists is because it reuses so many assets and the engine from TD and could make a good return on investment.
I'd rather take a good, low budget Kirby game over a lot of alternatives.
Kirby TD sold very well on 3DS, especially in Japan, not a surprise that they would want to get another out on the 3DS when it's performing much better in JP than the Wii U is.
That's true. Planet Robobot already surpassed 300,000 copies sold just in Japan so that's an excellent income. Easy peasy game to make reusing TD assets, add a few new features here and there and boom! Plus everybody loves a good 2D Kirby platformer. I might purchase it since I skipped TD and the robot mechanics sounds cool.
OT coming soon. Hopefully by the day's end.
Looking forward to it!
