Neat concept! I liked the innovation of having the next level button be something that is withheld from the player, and part of the gameplay - that's a really unique idea and an awesome way to interpret the "breaking the loop" theme. That being said, there are a lot of improvements that I would want to see in the game. For one, the slow movement speed got tiring at times and made the gameplay feel too slow. I also think you could've shown the next level button being broken more clearly in game, perhaps by adding cracks to the button, making it greyed out more, etc. This way, you wouldn't have to explain it in the game's instructions. As for the graphics, I think they were simple but nothing too special. They worked for what the game was, but weren't too over the top. I think the music was good, but I wish there were more sound effects for all the actions. This would help the game be more immersive and interesting to play.
Overall, great job on the game - keep it up!
