Simple concept but pretty fun. You made a lot of levels, and I enjoyed the challenge. The animation of looking left or right while holding a ladder was a nice touch to know which direction I will dash.
I got a bug on the first level with spears where I respawned but was still dead. I think a spear hit me during the respawn animation. I wish the respawn animation was a little faster, and it would be nice if the next level chunk appeared sooner. It would also be nice if pressing jump gave me a brief duration of unable to re-grab the same ladder, so that my jump wouldnt instantly cancel if I am still holding Up.
I made it to a huge level that I assume is the finale but I struggled with the tall ladder on the right.
Some sound effects and a walk animation would also have been quite nice to make the movement more satisfying.
