I liked the idea and managed to open the door on my 2nd run, but did at least 20 loops and managed to get past the steam only 3 times, and do the first jump only once. I still don't know how to get past the steam :( the first part requires knowledge and matches the theme, the rest just feel like luck and parkour skill...
However, the 3D models are really cool (I esp. like the enemies and the pillars in the corners), well done!
