Hi, I'm very glad to see your comment. Your suggestion made me realize that the difficulty of the game should be increased gradually, but the design change cannot be completed in a short time.
I just made some modifications to the game, including increasing the player's HP, showing the boss's HP, and opening all six levels.
I invite you to play it again.
I definitely prefer it now with the extra lives and seeing the boss HP, and it's good to see the other levels. One last suggestion to maybe experiment with, could the dash give you a few moments of invincibility even if you have to wait again to use it? I find it very hard not to get hit a lot by the badminton boss especially when the feathers are spinning (maybe I'm just bad though!).
