I like the idea but presentation needs work.
The actual game idea is solid and it works but needs additional bonuses or something to help with the point gap. The point total sometimes is too high to reach in 5 rounds and needs balancing. There should be more bonuses, the adrenaline stuff only appears randomly and there isn't a lot to get excited with gameplay wise. While the original Wheel of Fortune is kinda slow paced, I think Ring of Risk should be faster paced and really feel like you are risking it all.
The game screen tries to encompass all the elements. While the board is the most important, having the wheel (the ring of risk) off to the side and obscured doesn't look good. You can't see part of what's being spun as well the wheel itself should be a bit more than just red and orange. I think like WoF it should camera focus to the wheel while spinning.
The hostess just cycling through random animations, including karate chops is goofy and doesn't add to the atmosphere, which there isn't much. I thought when you lose she would kill you but you just get shocked. I think being shocked should be a consequence of getting something wrong.
there's no music other than the title screen, this might be a bug, But music would help the tension.
