My mouse cursor disappears within the boundaries of the game (when running in the browser). I could still play if I was patient enough, but the ADHD demands that I keep eye contact with my cursor at all times. Perhaps this is an issue of using Edge instead of Chrome or Firefox? I intend to download the game proper and see if that fixes the issue. Otherwise, the concept looks really good!

Edit: I downloaded this (for Windows) and the game works fine this way. However, I have difficulty with determining which games are "real" and which ones aren't. I suppose I should hand in my Gamer Badge and Portal Gun, because obviously I am no longer worthy of being a Gamer.
