Ok, after some extended playtime, here are my thoughts:
It looks great. There's no denying that for a cell phone game, it looks phenomenal. The backgrounds are gorgeous and the character animations are true to the original games.
Sound? Who needs sound? There isn't any in-game music, which is probably a good thing, considering the butcher job they did with Lumines Mobile. The intro music is like a tinny version of the original, but is a nice try, I guess.
I have a Razr phone and getting my thumbs to not shut the game off while I'm trying to perform platforming jumps that require far too much precision for a cell phone is a major challenge. And I don't like playing with the number pad because my phone beeps every time I hit a number. And seriously, who's idea was it to throw in tiny platforms that if missed send poor Bonk into a lava pit? On a console, with a real control pad that doesn't require you to jump and then push another button for direction, it would have been acceptable. But not here. The cell phone pad is the worst form of control ever.
But the game itself and how it's laid out seems almost home-made. Platforms are in weird places and the levels aren't very clever. There are some spots that take forever to get past because the platforms are placed so poorly. To be brutally honest, I've downloaded more cleverly designed fan made levels on MegaMan Powered Up.
Anyway, it's still nice to have Bonk back and on my cell phone. I think after I get used to the hideous cell phone pad (if ever) I may warm up to it more. Hudson, now that you've got this out of your system, it's time to get on with a proper Bonk game. This game is tolerable, but not the series deserves more.
