I enjoyed the game! The mouse mechanic was indeed unique, although I have to admit that sometimes I would've preferred being able to drag the boxes instead of the physics-based mouse. Maybe I just needed more levels to get used to it. :D The levels were enough to demonstrate the concept, but I would've liked to see a few more challenging puzzles!

Glad you enjoyed the game and thanks for playing! Yeah there are a few other features which could potentially make the experience a bit more cohesive here but since they're missing I understand how it might feel a bit off. Still, I find there is something special about not having full control over a mouse like you're used to and perhaps a different mechanic could bring that out better!
