Easy and engaging concept, nice and tense gameplay loop. Will reiterate what another reviewer said in that the bots were a bit easy. I'm also not sure what the value of obscuring the timer/sound of a bot, who presumably runs on some other logic than interpreting audio/visual cues. Also also, even when I purchased protection from modifiers, I still got hit by clock obfuscation in the round immediately following the buying phase? Not sure if that's a bug or if I misunderstood its functionality.
Regardless, still enjoyed it quite a bit. I think the core concept of using random modifiers to confuse or misdirect someone in a relatively simple timing contest is a strong one. Good job!
