A really nice idea for a game, the roulette mechanic was a cool addition that gave some extra flavor to the gameplay. The graphics were sharp, and overall it looks quite polished. Good job overall.
Now for some constructive criticism on what could have been done better.
Overall, I see a lot of work was put into this, but I think that development priorities were not set straight. Some aspects of the game were very well done and others were undercooked, leading to an unbalanced experience, which I understand can happen often in such short hackathons but I think is the secret in having successful entries.
For example, even though the visuals are 10/10, the game has no sounds or music. You would expect a game that looks this good to have some audio, because it really is a low hanging fruit to add. I even started checking if something was wrong with my setup. So, less time should had been spent on the visuals and more on the audio.
Same thing with the amount of content, I wish there were more signal types to have more options at each, and more troops, even if it came at the cost of having worse visuals.
One final thing, It would have been nice if there was a better explanation of the rules of the game. I know it is a lot to add in-game tutorials, but even something simple as explaining them in more detail right here in the LD page would be enough. You can even do it right now.
I spent a lot of time reviewing this because I think the game (and the team) has a lot of potential. Great effort overall, congrats!
