I improved the enemies to an extent that it is much harder now to make your way to the next door. And I removed the access card idea, need to make this much more visible and probably will add this in another set of rooms with a different theme.

Enemies now follow and aim at you even midair, so just jumping over them might not work anymore in all cases. As well sitting on a higher block is not safe anymore as you will get shot sooner or later. To increase the possibility to reach the next door I removed soldiers in certain rooms.

I would love to see youtube videos of a play through the demo, till the last unfinished room. And if I'm allowed I would also link those videos on my page. So go ahead and make some youtube videos and send me the link.
