I had a lot of fun playing the game! Here are some art related notes.
- The UI and the game art feel like they are from different experiences. The globe and units give off a serious game, almost military simulation vibe while the UI speaks to the bouncier flash games of the early 2000s. These can both work on their own but together its sending mixed signals about the experience I am playing now. There's a lot of design history to game art and UI it might be worthwhile spending sometime looking at ui on https://www.gameuidatabase.com/ when starting a project to put together a mood board. Consider looking at some games that share a more playful art direction while depicting world maps to match the narrative you are building, its important to have design precedents when creating the visual language of a game.
- When the characters speak together in the beginning of the game, I would get rid of the animation on the text and just show the solid text block, that or take the time to parse the string by word as opposed to by character to prevent a word appearing on one line for a half second before popping down to the next line as the rest of the characters of the word appear. It will make it easier to read and overall feel cleaner. Also some sort of portrait appearing for the different speakers would be helpful. This serves a dual purpose of communicating more about the speaker but also prevents confusion about who is speaking at any given time. Its pretty easy to miss the text box naming the speaker changing as the text rolls.
-I want to compliment your audio and music! Nice decisions here.
Overall the game was really fun. Great work!
