Great job on creating your game in Scratch! It has been a while since I used it, and is more for learning to create games more than anything. It's awesome to see you experimenting with new ideas. The mechanic of pressing a button to reveal doors is a unique twist, though the game could feel more like a maze if there were multiple paths to choose from or hidden areas to explore. Perhaps you could add more levels with different layouts, obstacles, or enemies to make it more challenging. You could also introduce a time limit or a scoring system to increase excitement.
Keep up the great work and keep experimenting with new mechanics—every idea is a good idea! With time and practice, you'll continue to improve and create even more fun games. Keep it up!
