I enjoyed the playthough, I would say the jump was difficult, but manageable. I could see why you would recieve some negative feedback on it.
I Jalex01x, sorry for the late reply! I maybe found out the problems about the jump, something related to the momentum (when you release the jump button too soon, the character just falls too much quickly, instead of remaining in air by the momentum). In the next games I will implement the jump correctly, much like I did with a previous prototype, "Daemon".
