The game looks great and the music is excellent. Too bad there are no other sound effect.
However it's extremely difficult due to unrefined movement on platforms and ladders. With a little bit attention given to that it could really be enjoyable. There is too much inertia when moving on platforms. It feels like sliding on ice. Getting on and off the ladders is wonky. It was my number one reason for dying.
Please fix platforming dynamic. It shouldn't be much work and can make a world of difference in respect to gameplay.
