Thanks for the extremely thorough feedback! its very much appreciated,
I agree that the game demo is quite difficult for newer players, this was an oversight on my part while trying to compact a whole game into a single level, when expanding the game, i'll be sure to make a lot more levels with easy transitioning to hard difficulty.
replying to all your bug reports, I agree with the fact I could've made more animations for falling and jumping, It just wasn't my highest priority given the time scale, i'll be sure to add those in when further working on my game.
and yeah the getting stuck in blocks is really common unfortunately, i'll try think of a fix to that soon.
Again thanks for the helpful feedback, its very insightful and appreciated
