Amazing visuals and cel shading!
I was a bit frustrated with climbing mechanics as it was not working as expected in ~30% of the cases (climbing out from another point, 90-degree rotation, etc.)
Would be really nice to have checkpoints, so if you fall in the middle of the climb you do not need to replay everything, especially if falls occur because of the weird collision with physics objects :D
I indeed see how this game can become a sweet and small climbing simulator, like Grow Home :)
Good luck with future development, worth time investments!
