Thank you! We did a bug fix as the enemies weren't spawned in correctly nor behaving correctly due to Navmesh building before navmesh agent. if you give it a quick try again, you will see everything is in its correct state now & alters your rating.
Fixing the nav mesh certainly makes the game more engaging, the way the little aliens jump out from behind objects and from the pits is quite charming. I liked how the enemies would force me to walk backwards towards the pits while i was firing at groups of them, it added a little bit more tension to it. Upon replay other than the game not being completable (which you guys are already aware of) the only thing i would say is that falling into the pits should trigger player death as I fell into one and had to reset.
