This was a good game but I think there are many bugs every check point. hope you can fix it & looking forward for your next project. here my gameplay... :)
1. I was caught after taking the ID card & after respawn I was trapped under because the door was closed.
2. I got caught after installing the battery & after respawn I couldn't open the door.
3. I was caught after seeing the door with the code & after respawn the door closed so I didn't know where to look for the code. 
4. I got hit by a monster ball & after respawn I couldn't press the purifier. then I give up because I need replay from the beginning. LOL
