I had some bars and clocks in early versions and I couldn't get them looking nice. I think I persuaded myself people would just instinctively know somehow!
But thanks for message. I was careful from very early on to make sure it would run in browsers - most of my development time was engine and shaders to make it fast
But there's a couple spots on some levels where shrimp can get stuck (floating point physics doesn't always play out the same on different browsers/machines)
