It's a very unique mix of the RTS movement mechanics and sheep-herding genre! I think it is frustrating due to a lack of polish (Souls getting stuck on the sides of the screen easily, but yeah we did only have 3 days to make these!), but it really has a lot of good things going on here. I think it could overall benefit from a slightly higher movement speed on the player units.
Once I realized that using patrol instead of ever leaving your units in place, I managed to get a lot more souls moving quickly! Also with the use of the approaching crescents movement pattern.
Also the movement in general was easy for me to pick up because I used to play some RTS, but it would have been a lot easier to herd them in if I had some of the other RTS features, like having my units assigned to the number keys for quick access. Players not familiar to the genre might benefit form having on-screen buttons for actions like patrolling as well.
