Wow this was a lot of fun to play. I rarely used the space bar, I am not sure if that would have helped or not. I messed around a lot with Mr. Boss. I would say that the text on the left side is a bit small and hard to read at times. The fact you made this in three days is impressive.
Five stars from me! You game is the third one in the video. I'm looking forward to more things from you.
