TL;DR: just play INKS instead, you'll have a better time.
The game has a nice aesthetic, including good visuals and music. However, if you've played other virtual pinballs (even ones on iOS), this app has some incredibly janky controls. First, the responsiveness of the left and right paddles doesn't always work. There are regions on the screen where the paddles do not flip, or flip very inconsistently, and you have to hold your thumbs in a very awkward position over what you want to see just to use the paddles. Second, the ball physics. It's... "sticky", is the only way I can describe it. When the ball contacts certain parts of the ramps, rails, and walls, it sticks to the board and slows down, especially right before getting to a paddle. This can make timing a shot very frustrating, as this slowdown is inconsistent.
Overall, I could see this being fun, but not when the controls are this bad. I'm a fan of pinball but had to stop playing after only three rounds- the controls were that bad.
