I love the overall retro/neon style, the tiles and their animations all look great!
One tweak I would suggest is that the building menus only show the production rate per colonist which was confusing at first, might be easier to understand by also showing the total you'll get per turn for how many colonists you have assigned. Same for maybe previewing the total amount each resource will change on the next turn. But the game is fun, visually interesting, and the core resource management is solid!
