Congrats on being able to do those attacks! There are more attacks than that in the game. If you are playing on the keyboard, you can press P and it will open a menu. If you are using a controller, you can press start. Choose "Command List" from the menu and it will show you every move supported in this version of the game. If you go to "Special Move Timers" it will all you to choose one of the moves and display the buttons you have you press underneath the character.
P.S. Still working on this game. Hopefully, you like the changes when I'm finished updating everything! If you have any suggestions, let me know!
