Wow, really had fun playing this! Some comments:
- Nice mechanics, each version of Gramps and his past self has their unique mechanics to help you get pass the levels
- Nice art
- I find it pretty funny that you can transform in front of the caretaker, alerting them & if you transform back to Gramps, they completely ignore you
- Nice take on having different type of caretakers. I got stuck after finishing the level with the red caretaker though
Good job on the game!
