People from the netherlands shouldn't make games, they smell too much like french fries
...
Kidding! I love the netherlands, especially the beachbars on your coasts
Your work shows a lot of "things done right, but its missing a certain impact"
Try to make scenes that "make sence". Ask yourself the following three questions while making a level. "Why would this room be here? Who would usually be around here, what traces could he have left? What happened?" The last thing is important for this kind of game. In screenshot 3 there is a bloodpool and a bludsmear like something has been dragged around there and then disappeared. What happened in this room. try to imagine something happening and then leaving the appropriate traces. If possible: try to use media that works well together (look and style)
other than that: reminds me a lot of my early work. Especially the image with the staircases
Keep it up
