Thanks again!
I'm really happy you liked the humor. Though subjective, at least i'm glad it works on the right target! :D
For the characters I'm lucky to have a friend who draws them, and for the tileset the only fitting one I found was Caz's.
For the maps I think I should add more secrets: I wanted to add some sort of secret paths, but as you said it can be confusing.
I understand the problem with spikes, it's never clear that they swap when you get near them or that you can dodge the one on the secret path, so the player might get frustrated. I think for that I should add more suggestions during the death scenes (or after), like i did with the tree after a tester got stuck on that part.
And for the ending, I wanted to do much more, but I kinda mismanaged my time and underestimated the work to do. So I opted for that cliffhanger. But I'll ponder different ways to introduce that scene.
