They made a big mistake following Mighty No. 9 by anything less than 2 months. Everyone's attention is on that right now, and their money too.
Two projects this big cannot compete in the same space. They're basically both highly praised retro revivals. However, against Inafune coming forth with a successor to Megaman? WayForward is simply not going to win that one.
I really hope this does go through though. My friends can tell you I'm a really huge Shantae fan, and it's the only reason I didn't completely regret buying a full priced 3DS after they cancelled Legends 3. Likewise I eagerly await the next one to release on the handheld. I'll be throwing my money at this Kickstarter in hopes it'll somehow, some way, make that goal and then some, but I'm not in a position to really dish out that much right now.
Oh, and, I hear Shantae is getting her tan back thankfully. Glad to see people were vocal about that.
