Good concept basis, may be a little too easy to finish but indeed very decent for a first level. I noticed only 1 bug (or intentional ?) : the last savepoint is a trap as it would infinitely repop player on a falling spot. ...

I thought it was a really nice level. It is very breakable though. Here's my first playthrough:

I sahre Mrs Ellie's position.
Another way to skip evrything in the level is to jump on the decoration blocks next to the three cube door. It is possible tojump on the small edge :)

Great level! There is a lot to like in this level. I especially like the free taxi ride home after going downstairs; the exploration is fun and there are multiple ways to get places.

I did find a game breaking shortcut though; I solved the level with a red, blue and green block and skipped the area with the save stones. It would be really nice to have 1 or 2 more save stones in the main area and blue block collection area, and the level could be a little more linear, but it plays just fine as is because it is small.

Overall really, really well done for a first level! The gameplay was fun, not impossibly hard, and good job on hiding that red block! Build more! :)
