I only have two major complaints:
1: Block puzzles were a bit buggy. I got stuck for a while because i couldn't tell the block was push-able because despite the pushing animation, it didn't move. No clue why this is though, as sometimes they will be pushed on first time, and later the same block would take a minute or two before the game would push it.
2: The controls on a keyboard are spread out. Would probably work better if you moved the interact from space bar to some other key above or below the ability key.
I also have two minor complaints. The first is the pots would hit enemies sometimes, other times it would go above them. I couldn't really tell when which would happen, but it didn't relay effect my experience.
Secondly, the given health just seems like too much. Health drops are a bit excessive, and heal a full heart, while most enemies only deal a quarter of a heart. This might be just because it is an early area, but even with that health drops could be toned down a little.
So, overall, I think it is an interesting concept, but still needs a good bit of work.
