Ok. Thank you for the report. I will change it with another hot fix.
Sometimes the problem is that you can't see the errors. I do test the level, but only random samples for the time being. Playing the whole game or every level takes even more time and I usually only do that at the end or when I have finished several levels. That's why I'm glad you're taking the time to do it.
So I will change the door (will only be a small problem)
For the spikes, I will make them further apart so it's easier to pass them.
Can you write me the level so I can find it faster?
