Nice game! I loved how relaxing it was while at the same time being an engaging puzzle game, and everything about the Fox was great.
As others have mentioned, I did notice the mouse sensitivities could get janky at times and objects could sometimes clip through walls (almost lost a cube because of it). One more bug I noticed is that during my playthrough (Mac version), my mouse kept on going outside of the window whenever I looked around too much during the game, which was a little annoying because I have hot corners that make my computer go to sleep when I move my mouse to the corner of my screen.
Other than that, great game!
