Thank you so much for the lengthy detailed feedback, truly means a lot for me.
On the visual side, my main inspiration was from "Chicken Invaders Universe" which admittedly is a bit goofy, however, I do prefer the space theme in general.
You are completely right on the AI/bots matter as well as the unplayability of the 16 player/bot version so I took a deep look into how the bots were planning and how the game was rendering. For that, I've just released the 0.2.9 version with which you should now see bots completing their turns around 20x faster, especially if you use the "Skip" button, a 16 player turn of bots should now complete under a second early on and much faster than before even with high unit counts.
On the UI and text copy side, yeah most of it was blurped together by AI which I will be fixing by hand in later updates.
As for newer features and roadmap, I want to arrive at a good spot for the base game and then start experimenting with newer features so definitely be on the lookout for that.
Thank you again for taking the time and effort to play and summarize your experience, it has helped me immensely!
If you are so inclined (and for others perhaps reading this comment later), check out the game on https://galac.site as well.
Mobile (both iOS and Andoird) and desktop (Linux, Mac, Windows) are coming soon!
