If I could, I would give 6 stars for originality. The game's concept is great, not only for its mechanic but also for its setting - a chaotic parliament hall.
Its execution, however, didn't fare so well, though it is completely understandable due to the short amount of time you all had. My voice wasn't really captured properly at times, and I really craved for an options menu where I could tweak the amount of screaming I had to do. Something I'd also suggest is to move the "Voice" gauge to the upper half of the screen, where my eyes were focused on most of the time. I'm tempted to also suggest a lower threshold of penalty, though I'm unsure if that'd be necessary if other changes were implemented.
In any case, this game has great untapped potential - it only needs some slight adjustments to really take flight.
