SImple idea but pretty good. I had a bit of trouble understanding the way the hammer works, but once I did the puzzles were fun! Good job!

It took a while until I understood how it works, but at the end I solved it.  Simple graphics, but nice puzzles! One thing of improvement: Perhaps it is possible to give the player another way of explanation, instead of text blocks.

Nice little puzzle - but i really struggled to understand how the hammer worked to break blocks.

What tool you used for that game? Looks interesting.
