I am really looking forward to see your video. Please let me know when you have uploaded it. Best you post a link to it here.
I'll try and get all the videos I have uploaded tonight! Will probably be another 6+hrs until then just a heads up
And a few things about the minor indicator glitch (I don't know what else to call it) that I pointed out:
1. It doesn't just show items, it also indicates the other players
2. They're hard to see, a little easier to see when zooming in on the screen. And easiest to see on the right side because they show up as white block-length sliver and the right border of play is the only dark border that they contrast well against.
3. When I highlight the play field (just highlighting the whole page works) the play area is then surrounded by a red highlight and **interestingly** these indicator glitches also show up as highlighted. So they then become small red slivers instead of white and are slightly easier to see.
I'm not a programmer but I think #3 points to two possibilities. Either these slivers are 'holes' in the interface allowing you to see through the game to the highlighted page behind, or if they're indeed highlighted themselves then they are some kind of text element.
Thank you for your report about what you found out about the glitches. The fact that the glitches can be also highlighted is a really interesting behavior. Unfortunately I cannot reproduce it on my system (Windows 10). I tried it with the browsers Chrome, Firefox and Opera (not with Edge since it does not support WebGL 2.0). I think I have to get a mac somehow.
Nevertheless I wanna thank you for your effort to upload the videos. As a dev it is always a rich (and sometimes painfully) experience to watch others playing your own creation. Especially if they play it more skilled than yourself.
