I liked the general atmosphere of the game, the nice ambient track and the graphics. I got some 2001: A space odyssey vibes from it (which is a good thing).
Along what has been said earlier (debug build), rather slow movement, I ran into an issue where I could not turn at all. Keys A or D did not respond to input, perhaps this is linked to bumping into stuff but I am not 100% sure about this.
Not being able to turn is a bit problematic as I have to face a door to open it so I lost time due to this. I think I had to bump into something in order to unstuck it....
One final technical note: UE5 defaults to the highest graphical settings which includes LUMEN, TAA and so one. This is fine if you got a nice graphics card but I use a midclass notebook to check entries and with an Iris XE iGPU I get about 15/18 FPS so its not a great experience. I do see this quite often with UE jam entries so it was kind of expected, just wanted to notify you that this is worth taking a look at.
Good job and thanks for sharing!
