Great work! Your aesthetic is really nice, and everything (from the fonts to the graphics to the UI) suits the sci-fi genre really well! I also appreciated being able to see unit information pop up on mouseover and how flanked enemy units were highlighted red.
A small thing I noticed: you might consider making your textboxes slightly larger. Some of the tutorial text appears to be cut off, especially the bottom few lines:
I am also a huge fan of tactics games, so I had a good time. If you keep working on this game, I agree with the previous comments suggesting making some enemies target the bomb carrier and/or adding a countdown to when the bomb will explode so that it's harder for people to turtle or keep the bomb carrier all the way in the back. It may be nice to also provide an option for a grid overlay so players can more easily count movement squares/unit ranges.
Thank you for sharing your work! I especially appreciated the sound effects you added (I kept laughing hearing the enemies fight each other), and the victory screen is a nice reward as well! Can't wait to see more from y'all in the future!
