Glad you liked the game! What do you mean by color contrast, can you please explain more?

Sure.
So I have a background in Frontend WebDevelopment with a focus on accessibility. As such, I developed a sense for low contrast (next to other things). You’re using gradients for your tiles and background, but approximate them to https://contrast-ratio.com/#%23fdf400-on-%23ca9300 you can see, that the contrast is too low.
That means, for some people it will be hard to tell apart what is a tile and what is background.
You could play around with https://coolors.co/ca9300-fdf400-fe3100-2c6e49-08415c (after locking the colours you plan to use) to generate a colour palette, that might work out better. (Hit space bar to create the next colour combination).
