I love the Super Monkey Ball Concept. One thing that I think really stood out to me was that the aesthetic of this game really does look like Super Monkey Ball, even with just the default assets. I could tell you spent a lot of time trying to make that look right. I also really appreciated how the timer worked perfectly and reset correctly, and so did the gate message, disappearing after a few seconds. I played the experimental build because I thought it might introduce a more interesting mechanic with camera movement. It is definitely more fun and responsive to steer the ball by turning the camera, but I think there's definitely some ways to make it so it doesn't freak out on collision or when the player tries to go backwards, so take another look at that. I also think the game needs more challenge, the obstacles don't provide any challenge and the player can go right around all of them. I think if you simply made some bigger, or added more, this would help your game tremendously. The maze is the best part of the current game because it provides the most gameplay. Lastly, I think I might give less time on the timer because it's very generous. Perhaps finding the best route to complete the level is the challenge of the game and the player needs to run out of time a few times before they can actually beat it. Another thing I found very successful was the checkpoints and resetting of the ball, they functioned really well. With a rethink of the obstacles and some fiddling with the camera, I think this would be a really fun game!
