Wow. I've finished it. It was huge! I have mixed feelings. For the most part, I enjoyed the level. I liked multiple endings and the huge world. On the other hand, I've never seen so many clones of the same challenge (mentioned above by lamarblake and PP) in my life. What was worse is some other screens, like luck-based ones, or green button with a runner animal and a shooting fish. E.g. the cannon in x1013y936 kills you 75% of the time no matter what you do. It felt like a Very Hard level with a number of broken challenges. Sequence of screens starting at x1002y1022 was a bad joke. God bless Nifflas and LPChip for the cheat
First mistake was a glitch too, x985y1014 didn't contain the small platforms it has now.
Keep up the good work and design challenges more carefully and creatively in Descent To Hell!
