I went back and forth on it, and I would normally agree, but I couldn't really think of any other ways to make these two harder.
At first I set both up with default warnings and very very tight tilts, but they played like that TWD Pro from LAX this year and I think that sucked. also that damn debounce allowed big moves, while little moves tilted out.
So I loosened the tilt a bit to allow for some decent nudging, but nothing crazy, then dropped down to one warning. this made the game times a lot shorter, but I didn't feel like I was getting cheated ever by the tilt. The first way I had it did.
I am all ears on other ways to make these two more difficult though.
