an easy to pick up and fun game. I especially liked how, in the first level the game mechanics were explained to the player whilst playing, through text that ran above the game.
A few small changes that you might consider:
- A "restart" button for instantly restarting the level when you screw up in the beginning, instead of having to either lose all your health on purpose or exit out of the game and restarting manually
- Some short of visual indicator to let the player know a rewind is going to occur. It doesn't have to be a long time before it occurs, even just a second before would be fine. At the moment, you have to either rely on luck or memorize exactly when they occur if you want to evade them, as you do often not have enough time to reactively move out of the way of obstacles.
- Returing a bit sooner to the home menu when a level has ended and obstacles stop coming; the game continues for some 5 to 10 seconds with nothing happening before returning to the home screen. You could add some sort of finish line to visually show where the end of a level is and have the player instantly return to the home menu after running over the finish line.
