For this jam, I used a personal game kit which already has crouching, and there wasn't a need to take it out. You're right about the running, but if I made the player move that fast without the sprint button, the player would feel unnaturally fast without the context that you're running.
I did realize an alternative, and much better, method I could have used for the hitboxes, but sadly that was only after I had submitted it! I'm sorry about that! The hitboxes were on the particles themselves, but in hindsight, I realize it's not intuitive enough! I also didn't really intend for the game to be improvement based, more just a one and done thing, really.
Thank you for your feedback! It's great to have more I can improve with the game!
