Hey there thanks for playing!
I agree with your point about the controls, there are a lot of overlapping actions and its not really clear what does what.
I think jump needs to be be kept a separate key otherwise it conflicts with ladder climbing/ladder mounting. But I should at least mention it in the tutorial.
S/down should allow you to pick up and drop pots, but I have been having some issues with the tutorial section causing that to get bugged. Hopefully should have it fixed today/tomorrow.
