Game still ran poorly with hardware acceleration on Chrome. Still, game cannot run smoothly. Why? I don't know. So I tried to see what was affecting. It turns out it was affecting RAM, by a lot!
I am surprised by the results. I have tried with my browser up to date and before update!
Before update it peaked around 870-880 MB of RAM.
Now, with updated Chrome to new version, it peaked to 950 MB of RAM.
This increase of RAM usage may be due to new version of Chrome, but it's a gap around 70-80 MB. I don't know what else I can do.
I tried running on Edge, but I get same results.
I'm deeply sorry, but I can't play your game.
