Also found that while the roulette is spinning if you return to the inn menu, and then re-enter the roulette menu, the Spin 100 button can be pressed while the wheel is moving. Pressing Spin while the wheel is moving makes it really easy to pick where the pointer lands on the previous spin.
Lastly after maxing out the jump skill, I was somehow able to perform a super bounce that gives you maximum upwards momentum for a bit, which at the max height can sometimes take you all the way up to the ladders and shields section.
It was a bit inconsistent how high I needed to be at first, but I found a somewhat reliable method if you need to test for bug.
- Max out the height of your first bounce
- Then climb up to the first crab and get on the crab's raised pincer
- Jump off and try to land on the ground while spamming the jump button
- Most of the time I got the super bounce from this height, or by jumping off a higher part of the stage and avoiding all the platforms on the way back down to the ground.
