Thank you for your feedback! Indeed, we are currently implementing sound to the game. In the next months I'll be posting an update with some major changes to the gameplay.
Regarding your feedback, we'll look into making ultimates more clear once they are available and later on there will be a unit details panel where you'll be able to see unit stats.
You brought up a great point, which is the direction bonuses RNG. This will be toned down, so they will be either semi-randomized or fully hard-coded.
This is a passion project that we've been working on for an year, so thank you so much for playing :)
