I find those errors you wrote about - i fix them by adding hazard cube on the top of the level. And i added roof for last doors.

Thanks for plaing and testing my level.

This level really evolves, when you said 5 min i thought it would be pretty quick, but once you get to the part with the platforms it really gets complex, nice job! While i was chasing one of the platforms and collecting the blue energy cubes, i lost the platform and was able to climb onto the roof and by-pass the 3 energy cube activatable door and reach the end withouth opening it, i just climbed over it, i still had to open the final door, but i had enough blue energy cubes by then.
