Yeah, unfortunately we had troubles in the last 3 hours when we added the maps to the game and we resolved all the bugs 1h30 after the end of the jam :(
I did not have problem with the enemies spawn, maybe you did not find them ? There is one ghost and one human at the first level, then, after going into a door you will get to the second level and have two ghost and two humans then three ghosts and three humans [...]
It can be long to find them with these big maps ^^'
Thank you very much for posting a comment about this game ! :)
