Thanks for playing. Currently we are testing only targeted features/gamemodes and for that reason you can't play everything right now. The green icon is a signal about the timer has been ended (I will change that to something else). I forgot to activate the quit button so that will be fixed. About sounds, I will reduce the sound. About image resolution, I don't have idea why it is always like that, maybe the engine rendering isn't the best but I will try to fix it somehow.
