Randomized I can handle, timed will be frustrating, but the sheer amount of similar images assaulting my eyes makes this impossible. I made it to 11 at best from luck. My advice is to tone down the volume if you want to make similar symbols. Make 8 that are similar out of 16 rather than a whopping 36 images with more than a dozen look alikes. The animations while nice are NOT worth the frustration. If I might suggest, make a combo for sequential picks within 5 seconds to add to the time limit. At least a few seconds extra would be more merciful than this unforgiving countdown. Difficulty is all well and good, but timers add artificial difficulty to a game of this concept. There's no way to know how, when, or where the orbs spawn, therefore you're guaranteed to fail until you get good rolls, have a photographic memory, or have eagle eyes. No one likes guaranteed failure.
