The game is overall VERY well-polished, but for some reason it was really laggy for me when playing on Firefox. I quickly understood what I'm supposed to be doing, but I would have a delay between pressing a button and my input actually registering (the input duration would also be extended, so I would often overshoot the console panels when walking). This caused some frustration and after something like 7 attempts I switched browsers. After switching to Chrome, I got it on my first attempt :D
But yeah, the idea is super cool, the art and game feel are excellent and I really enjoyed the game once I managed to get rid of the lag :)
