Thanks for taking the time to make a full video, all the complaints you had were fair.
We had to cut the game short, it was submitted 6 minutes before the deadline. The collisions in the level were made within the last 2 hours of the jam, so that should tell you we were really pushing to get it done. XD
There is no lives system, you regain your light if you run out normally, but if you do while being chased by the enemy it's game over. And you did reach the last room, it's a fixed game over. That wasn't the intention at first, unfortunately that was a compromise we had to make.
