That was fun. Really nice concept and implementation as well.
The gameplay while simple is fun, and it doesn't take anything away from the experience.
The sound design is well done. Especially considering the bomb doesnt have a timer but rather it's indicated via sound, which I love personally.
The art is minimal but it still fits the game.
The only critique I would have is the enemies themselves, as some have multiple lives and some don't, which could be just a design choice, in which case I don't think it's too bad.
Overall it's a simple game which is lovely to play and is fun.
