Really nice game! I like the visuals, it all fits together and creates quite a relaxing feeling (that disappears as soon as your character dies). It took me a few levels to figure out what all those different temperatures on the screen mean, but after that, it felt quite intuitive.
The only thing I would change is perhaps the controls. The game pace is quite fast and to change an item one must click on it, drag on an empty spot in inventory, click on another item and equip it with another drag. If you drop the item when the cursor is in a slightly wrong position, it goes back. I think just drag & drop from inventory to character and vice versa (with possible slot swap) would feel better.
