Incredibly unique game. This game did an amazing job at incorporating this Game Jam's theme, "only one" by giving you one bomb. It's the type of thing that sets this game apart from the rest.
Here's one thing I had a gripe with: visual clarity. I don't know if it's just me, but it was kinda hard to know which is which in the very last level. I couldn't really differentiate the background from the foreground, and it felt odd. I feel like, in general, the background (specifically the windows, pipes, and the pencil shaped objects) should appear faded so it looks like it's in the background and is uninteractable, since it became confusing to play the last level when it was like that.
Other than that, it's a really great game! I enjoyed how well-thought the level design is and the thought process that went behind the levels. Really unique game with really good level design too.
