The customization system gave me so much freedom---it is basically just an art canvas integrated to a customization system(Which I am surprised that you implemented it this well).
The customizations themselves are great--the different brushes and the colour slider gave me a lot of options. Definitely one of the customizers with the most player potential.
However, even when I followed the engine placement guide, I still could not get the engine out to be placed. Therefore, for the rest of the game, I had to watch the video. However, I rated it purely on the customization system, so no deductions there(since it's also probably my fault)
Great job!
