Yes, it very very strange!Cannot be upgrades fault for sure,cos all of them run through same code.So if one of them broke the game,then others will be doing it too.I even tested in one of my runs, some days ago, with 75 or more reaction,but game never broke.Maybe its addblocker,cos i dont have one on both my browsers.Its something to do with scene transitioning,but that and how is a mystery :)
Again, thanks for feedback,too bad i dont know how to fix it! Maybe, after some other projects in Godot for browser,i will get thats a problem here.
Time will tell.Have a good day!
