Thanks! Balancing the difficulty is quite challenging. I feel like it shouldn't be too hard to beat the game after a few tries but it is true that everyone is different and may find the game more or less difficult. Also as KevEatsCheese said, the time between each try as you have to come back down is too long, so each loss is too punishing. If retrying was very fast (you restart instantly at the bottom), maybe the eventual difficulty would not mean so much because you can more easily try different approaches and learn how to beat the game.
Reloading the page is totally not the correct way to make the player restart the game haha but I was very tight with the time and coding a reset functionality (which should usually not be that long) was not in my priorities as I knew a reload could do the work and had to code the intro/end at the very end of the allotted time (I had to pull an all nighter to finish the game). I will probably update the game after the jam to fix that.
