Thanks for your comment and the feedback! Did you play the game in fullscreen mode? I think that should help a bit with the size of the cursor, but I do see the problem, which is definitely not how it looked while developing in unity :D
err well, honestly I kinda avoid full screen mode because I have an ultra-wide and most games (my own developed games included) get really borked up on it. aaand yep, I know what you mean about browser != in engine LOL. thanks for the experience, I enjoyed it!
