I really liked the interpretation of the theme in 1D. It is really unique and creative, how many things can be represented with just points on a straight line. Although, there is still room for improvement but is really good for a proof of concept. One thing which I think can be improved is the color gradation (as it was quite hard to distinguish between objects) and a tutorial might have actually helped a bit to figure out things. Anyway, an amazing idea! I hope you take it to next level. All the best man!
Also, if you have some time, please play and review my game. Thanks!
