These are parts of a visual design document we had to edit about a Twinstick shooter while also adding some custom ideas of our own.

This was something I added because I thought it would be cool to have a teleporting ability like in Mr Shifty.

Adding abilities was also something I really wanted to add because abilities make games so much more fun, the customization is super fun for both the player to play with and for the creator to just let their mind run wild and add a bunch of small optional ways to play the game. You can have active abilities that the player must activate, like a temporary speed boost or damage buff or anything like that. You can also have passive abilities that can make the game harder or easier, like health boost, speed boost, or hardcore modes.
