as noted on the game page (at the time of writing this), there are possibilities of different browsers/plugins/etc causing overtly janky/broken looking things that you can see but I cannot. If you encounter anything like that (garbled UI, something overlaps, spazzing fonts, flickering elements, objects scaling out of bounds, etc), feel free to complain about it somewhere. 

an example of this is that the game uses emoji icons for visual anchors, but different people will load different emojis in different environments, creating weird situations where certain icons are using 2 emojis instead of one, or simply making the used icon look weird for what it is (in general they should be vaguely relevant, but mine are way cooler) 

realistically, idk how many of these 'compatibility issues' I care to solve compared to just making a more badass game, but if the information about what is broken is laying around already then it's a lot more likely that I get around to fixing it at some point.
