The game itself is super fun and addictive. Most of the issues are with the specifics in the app. My suggestions: Allow for muting of sound within the app. Please!!! I'd love to be able to listen to my music or podcasts while I play but I can't mute JUST the in-game sound. Allow for locking screen rotation, or, in the very least, have it follow the OS. I would play this more if it did this... The auto rotation drives me crazy. Landscape mode is so tiny it's practically unplayable anyway. Provide a colorblindness mode. I use a red screen filter at night and the cyan and green balls are basically indistinguishable making it unplayable. Otherwise it's an awesome game that I really enjoy. I still play on the website sometimes because of these features specifically, but would prefer to use the app. With these changes I'd happily give it 5 stars across the board!
