I like the simple art style and the puzzles really creative :). But I really missed being able to sprint. So ways felt too long.
Also it would be cool if there were multiple solutions to puzzles. In one of the levels I carried both items with me. Meaning: taking one, move a couple of meters, drop and get the other one, REPEAT. There the long ways were really painfull. I knew which item would do the job but I wanted to know if the other one would work as well.
