First- the cursor fix you described didn't help (I believe that setting Cursor.lockState = CursorLockMode.Locked would fix your problem though).
The puzzles were pretty good. Other than jumping on AC units with strange perspective they were pretty enjoyable and logical. Nice.
Although the graphics were simple, the effects you used added nicely to them.
What seems to be missing is the "fight" part of the "street fight".
Over all- I'd gladly play a longer puzzle game designed by you two.
