Hey man! It is a solid first jam and you can be proud of it. I would just give the player a little leeway in the way of making colliders more forgiving, and maybe giving them one free hit to take. Something along those lines.
Keep up the great work! Here is my first jam attempt too if you are willing to give it a go and let me know :)
