Ok it works now :D I went through few levels and now Im in that castle level (if you want these poor zombies on screen go through the gate, you need to set forcesimpleobstacle = 3 in fpe file of the gate asset, then AI will recognize its polygon shape)
In general I'd say this is a nice little game :) Simple, yet enjoyable experience.
One rather irritating thing is stock gameguru heartbeat sound when player is hurt.
I'll play one more time tommorow, and give u some more feedback :)
