Finished the game! Like others said, I feel like the platforming is quite hard. I also felt like the hard level was easier than the medium level? The hard level doesn't have disappearing platforms which means that it allows the player to recover. Took at least 10-15 attempts on medium but got it 1st try on hard. Was interesting on medium, where I needed to roughly plan where I was going, since platforms disspear quite quickly.
Overall feel like it's a great game with nice graphics! Just improve on platforming and it'll be even better!
