You can use beepbox.co for retro games or just some bass but you can also FL studio but it has a bit difficulty curve.
Thanks @SGGGames I know the movement is a bit floaty but this was kinda like my first platformer game. I will regularly update the game.
Thanks for your response and I know that the game is short but I will bring updates to the game in future.
Everyone who will play the game leave a comment to which I could improve the game
