These mechanics were very interesting but maybe a little too hard to figure out without a list of the controls. I feel like there must be some additional buttons I'm missing because there are several challenges I couldn't get past / rewards I couldn't reach even in the very first section of the game. There was one instance where I felt really smart figuring out how to climb up to an area with ice blocks, only to find that in order to get the treasure I needed to be able to shrink (but couldn't). And there was no way to apparently get up there without the blocks.
