This is most of my progress in 1 hour 15 minutes of playing the game, so far. Only Stage 1 Isnt shown since the difficulty doesnt really start to spike until Stage 2. The last half of Stage 4 is pretty tough. The Difficult Game Sections playlist usually focuses on the hardest sections, but this game only has 1 checkpoint per stage, so decided to just show all the areas I completed , after the first stage which was relatively easy.
First death at each new checkpoint shown, but the rest are edited out. This shows some positioning tricks I found , especially on the bosses. Full playthrough and tutorial, review videos will be up whenever I finish this.
