I seem to agree with the comments on the great weight to belly ratio XD, and the speed being a bit lower but I did want to add that this would also help if it applied to the jump time, as in how long it take for you to go from having started the jump to back down, because that felt a bit too fast to control. Also had a good bit of difficulty holding shift, up, (left/ right) and jump for the climbing section and sometimes due to there being a restriction on some keyboard on the number of inputs, it meant not all of my inputs would register. So I wonder if it would still be as fun and difficult if you removed the need to press up to stay on the wall while climbing, instead having it so you fall only when you run out of stamina, like in celeste?
It's just an idea ofcourse, I think the game is great! Nice work on the art, music and the concept! :))
