Sounds great! However could you please make the bosses move to where the 0.1 bosses were staying for the first attack rather then letting the player do multitasking while figuring out the patterns and the movement behavior?
I'm thinking of only adding movement after the first few levels - so after the player has mastered the dodging, they can attempt to handle movement and attack. Not all bosses will move though, and bosses that move will have a easier pattern depending on how difficult the movement is.
Maybe also put the payers name there?
I'm still learning the gist of the engine, so I don't quite know how to make typing inputs yet :) Player naming would be a lower priority compared to game mechanics though.
