Thank you for the feedback!
Is there anything in particular you struggled with the puzzels? Was there a mechanic not explained well enough? Were you confused about what the goal of each level was? Were there too many choices to make and got choice paralysis? Were you confused about what button/switch was attached to where? Was the platformer too heavy for a puzzle game?
Was there a particular reason (which can be improved) the puzzels were hard for you, is what I’m asking.
