Overall, this game felt really polished and complete! I just have a few nitpicks I think could make the game even better.
I think the music used during gameplay was a little too tame, and almost felt like it was trying to lead to something more intense. I think if the gameplay music was extended to include a more intense loop following the current song, it could've helped the game feel a bit more exciting.
Additionally, while I really enjoyed the toast mechanic, I think it could've been expanded on with some sort of timer to pressure the player to use the toast instead of holding on to it for later. Maybe this could reuse the idea of burning toast?
I enjoyed the intro scene pushing players to burn the toast to start the game, I think it added to the overall feeling of the game by providing an interesting simple story to give it context! It would be fun to see that tied into the gameplay as well.
