My max score is 8, and I tried 10+ times. hahaha your game is tough to play, it can get frustrating fast but that's not something to be demoralized about. It happens. You can just get more feedback and then improve as you go. Good first game jam submission.
You can take a look at my game, I think I did a good job with the difficulty balance/progression at least, maybe it can help out. 👍🏾
