No problem! Helping developers with feedback and ideas is always a pleasure ;)
Here are a few notes that might be useful if you want to continue the project:
1. There should be a button to change the screen resolution (window mode, fullscreen)
2.- Likewise, there should also be a button to exit the game from within it
3.- There needs to be some balance between stages, since some are either too easy or too difficult (for example, the ones where you have to press buttons in order could be redesigned or rearranged in the levels section)
4 (though this is just a personal preference) .- A final victory sound! When you reach the end, it felt a bit empty, and it would be more enjoyable and satisfying to have something to greet you there.
