The concept is interesting, the 1-bit style works well - I like that green color shows the foreground layer to help navigating.
The controls are not very comfortable and some of the game mechanics are not well explained, so there was lots of confusion on how thing work and why I fall from the window e.t.c
I think that more freeform platforming gameplay could make the game more fun and addictive with the same visuals and game goal.
