Ok, so I like the game, I want to like the game, but you need to have checkpoints. This game isn't nearly as much about the platforming as it is the interesting enemies and making sure you don't get hit. I really like how the coins are actually useful during the game play. I unfortunately had to quit after dying (probably near the end) and restarting a lot. Citing "skill issue" is kind of insulting too.
Only technical issue I saw was that when i was on the lowest platforms, the UI for the rust bar was covering my character and the enemies and made it difficult to see.
