Thank you for the review! In regards to the window size, do you mean it doesn't scale when you try to drag the window to resize/ press the maximize button? If so, it's not able to be scaled that way. Sorry if that made it difficult to play with your recording software. The only two options are either 640x480 window or to go full screen with the F key.
The camera controls are designed that way so you have to choose between measuring or moving at a given moment, but I will keep your idea for a marker that shows where the Boxy Hop-Dog went to in mind!
Again, thanks for playing. You're the first person to ever make a let's play for one of my games!
