Thanks for the feedback! I just pushed an update based on it:
- The hit flash is much softer now. For normal wins it only glows faintly around the edges. To make up for it, I added some gentler effects instead: ripples around the sphere, a lamp light that runs around the frame, and a "+score" popup.
- Hit, miss, and jackpot spheres now have different shapes (circle / diamond / star), so they can be told apart without relying on color.
Thanks for pointing out the monochromacy issue. I hadn't thought about it. If anything still looks hard to tell apart, please let me know!
