Hey, nice game!
I would say that it’s treasure hunting with bombs which were so nicely done that make this game stand out for me. I like hidden secrets and completing things, so I was looking for all those breakable walls all the time.
Final boss fight was cool too, I was struggling at first until I’ve figured out the simple tactic with which I can defeat them and after that I got to the credits!
One thing to note is that I think level exit should be marked differently and probably placed quite specially, as I’ve exited from the 3rd level before I really wanted to do so as I haven’t noticed that I’m stepping on the level exit “marker”.
Great job!
