Very difficult!
I loved the art. Very chill music. Nice animations, it played well and smooth.
There seems to be a climb limit put on the player, but it's not time (as far as i can tell), so I was never sure when i was going to fall or not.
A few bugs as mentioned below but nothing too bad, though I couldn't help but feel like the character jump was a tad too floaty. I took damage a few times because he didn't jump fast enough to clear their heads in time. Maybe I just need to get good though :)
