Another valid criticism and points to note + Yay! You know BN and OSFE!
By looking at this, yeah! The delay is kinda long between the abilities, but that wasn't on plans since originally you would recharge after using your abilities. But in this version, there's no delay between using your Abilities to a Weapon so you can combo with for example: A Wind Racket into a Pistol Saber! Also, OSFE was 4x4 iirc. This project is still pretty scuffed but these points you noticed always gets a smile in my face! I'll aim for continuing and tuning the project since (just like my prev jam game) I liked doing this but there's always an unfortunate situation that messes my scheduling and it derseves a purposed version!
And... yea, I kinda have the same issue with OSFE when I have a deck with too many abilities.
