Very cool game. I love the artworks for this game. Also the different bomb types are a very cool method to bring variety into it. I encounted some bugs (hopefully it's only on my end).
The first one was in level 1: The bombs just stopped appearing and I was stuck with 11 bombs left. After restarting it worked.
In the 3rd level I couldn't press the bombs anymore. Thankfully you implemented a save option and I had not to play from the beginning again.
Still this is a very cool game
