This is really fun. Thanks a lot.
If I only could request one thing, it would be record times per Stage. Then me and my wife could challenge each other every day to see who can get the better time in a stage. I think this would lend itself perfectly to this game.
I don't even mean a "beat this time per stage" mode (I think that could introduce more stress than anything else, and would be a lot more tedious to implement), just a "your best time".
But even without that. This is already great.
