funny story, I didn't realize in my first game that friendly fire was in the game, so i just accidentally killed half my teamthinking my bullets would go through them instead.
A tactics game is neat, and it's impressive that it's done in a jam period. But It's very hard to see what's happening on the enemy turn or the bullet phase. Adding an option to slow those down would help a lot. Another thing is that units are very hard to distinguish. They have distinct faces sure, but their icons are so small, and all in a similar colour, that they are hard to make out. Some clearer and more distinct icons for units would be good.
As someone else said it is very hard to make tactical decisions in the game and usually ends up being a bigger number wins the battle. But I don't really know what to change to make it more. I'll just throw some ideas into the ring. Maybe give the player more info to work with? Stuff like how fast every type of bullet moves per turn, the movement of every enemy. Maybe ways to shoot that aren't straight lines. Adding some terrain to maps could also work.
One of the cooler units is the laser ones since you can plop those on the top and deny your opponent an entire section of the map. Perhaps make the game more focused on area denial?
You could also add an additional phase after the bullet phase, to see what bullets your opponent fires, where if you have spare command points, you could move units that haven't been used out of the way, but they wouldn't be able to shoot. To prepare for next round.
