The incorporation of time reversal in a clocktower-based platformer is brilliantly executed.
Using the stopwatch as an informal way of monitoring the passing and direction of time while the surrounding phenomena can be reversed at the player's will adds a layer of puzzle-solving for each level with rotating platforms and button keys that unlock entry to the next stage when pressed by a weighted object.
The presentation in both the game and the Itch.io link fits the clocktower ambiance that ties into the jam's selected theme. The sound effects also provide feedback to the player jumping around moving parts of the clock tower. The vintage music is icing on the cake.
The platforming controls merely involve horizontal movement and jumping while time can be reversed with left shift. The player can also reset the level with the R button in response to an irreversible problem.
