I see you had problems with the deadline and uploading your game.
Nevertheless, I played it due your given link.
The concept is good and reminds me a bit of "unfair Mario". The music and the SFX fits also. But the equalized voice was really annoying. I know that it is intended, but I can imagine that this voice can be a reason to quit the game.
I saw the hidden place in the main menu and was able to finish on easy. But on normal I wasn't able to find the correct way.
