Great job on this game Gus! It feels complete and the idea is quite clever. I couldn't really see how the theme of 'time travel' was used but that might've been something in later levels.
What was good:
- Includes a menu which makes it feel polished and complete
- A story!
- Only very minor bugs encountered.
What can be improved:
- The difficulty is quite high
- Collision detection is sometimes a bit off
