Very nice simple puzzle game. Me being dumb, it's rare for me to have fun playing those types of game.
Artwork works nicely, music and sfx are the same.
Having to die to go back to the menu, and the bomb button being red to proceed threw me off, but those are nitpicks. Maybe also having to drag every piece is a pain, using the scroll wheel to choose which part of the rail to use would have been nice.
