That was cool! An Unreal Engine game in just 3 hours? Wow!
I love the interpretation of "chosen one" as "chosen test subject". I could easily see this as a portal-inspired physics puzzle game but without the motion sickness I get from games like portal. I liked the idea!
I think the one thing to keep in mind for next time is that the navigation was done with ZQSD instead of WASD, I understand that you're probably working with a different keyboard layout in a different language though, so it's not your fault. An easy quick solution for next time would be to just make W and Z as well as Q and A do the same thing, or add the arrow keys. Other than that I really enjoyed this atmospheric little game! :)
