Nice game! I'll just add that the aim assist thing that you added was a good idea (even if you were going for a harder game), you might know this, but usually designers/developers add secret aid mechanics in their games to make them feel fair, even if the odds are stacked on the player's side. Here's a good video by Extra Credits that goes into further detail if you're interested (and even intentionally challenging games do this often, for example Celeste's harder parts). That's why we test stuff beyond even bugs, and let me tell you that you're on the right path. Good job!
