Looking at your game what I would want to do is run backwards non-stop, so if I were you I'd position the obstacles far from each other to maintain the action going, or it could slow down the pace of the game

• I Didn’t add a settings menu. Is it necessary?
• How many level should I add?
• Did you find hard time playing the game?

You forgot the super jump! Go side of any platform and do the super jump. It is the core of the game.

I didn’t put any instructions on the first level as if the game is starting from the last level. But I will make a seperate tutorial level to understand the basic mechanism of the game.

As the theme is Rewind, which also means reversing, so I made the game’s flow reversely, literally. Though there is no recognisable ‘rewinding time’ which means back to the previous state, but the whole game is basically rewinding, I mean going back to it’s original state.

Huge Thanks for taking your time for checking my games.
