I liked the game. It got a bit too much running around trying digging everywhere. Since the back walls had some maze like properties, at first I dug a lap around the outer perimeter trying to find a way out that way. Then when I was more or less done with that quest I found the statue and the real quest.
I think for me it was a little too much digging around to find the things. One way could have been to make the game smaller, another might have been to give the player some indication of how far away they are from the closest stone/crystal thing and keeping the level. Or giving direction. The crystals could be humming. The hammer might have some indicator on it. Or it could be a UI feature.
It was very satisfying when I managed to chain several bombers in a row.
I’m also very happy that death was not the end of things.
It would hav been very nice if I could have trashed the initial room too btw.
