Thank you so much for your comment and the feedback! <3
Those are all very valid points. I was a little bit short on time because a lot of things were new for me (my first own plattformer that's not just follow a tutorial).
The first weapon is a plus whip to add tge letter to the letterbox. The second weapon erases the last letter from the letterbox. I agree that they feel super similar. I got the animation a bit late and just had to somehow get it in quickly.
The volume should be a quick fix, I will take a look at it asap. For the weapon I gotta see cause the character + weapon are in the same animation frames. Should be able to pull them apart though.
Have fun playing the other games! I Very nice of you to leave some feedback!
