Hey @s-wolff
I’m just following up with you on this.
Does your chromebook have a touch screen?
As the mouse pointer in your video is your operating system’s graphic.
Gems of War has a custom mouse pointer graphic. So it appears your device isn’t really recognising the mouse properly.
I would suggest ensuring your mouse drivers are up to date as well as ChromeOS.
If this doesn’t work let me know and I’ll pass the info onto the team.
