Nice clone Drew! Your rodent is appreciated. The UI dressing around the edges is super faithful and well made, as are the textures for the spinning portions of the game. I am impressed with the extent to which you matched the feel, tone, and visual style of the original because in my opinion it is a visually complex game. I do think that I would appreciate being able to move my cursor more quickly, but the speed of the blue obstacle cursor still matches my own which I think helps mitigate that somewhat. I was sometimes unsure why it felt to me like I could get some objects up to speed easily and some I could not, particularly in the DNA welder, but personally I feel that the source game is a bit lacking in feedback, so this may not be unique to your clone. The thing I enjoyed most was when I could get a particular object spinning really really quickly as it looked cool and was also helpful in allowing me to focus on other objects for a time.
Well done with this clone!
