Congrats on your first game jam game. Over all its fine. Some tips though, Movement could be bit faster, or maybe using velocity since now it feels a bit static. Also rewinding could use some indication that its happening. Keep it up :)

thanks for the feedback, the movement thing is a bit intentional because of the bullets i didn't want you to move too fast and overall that the game won't be too fast, about the indication you're absolutely right it is an important thing, i did however made it so the music will play backwards when rewinding but graphical indication will do good
