Really solid puzzler - I can see how additional features / moves / hazards would make this very challenging on a Baba is You way, so good job on a solid foundation.
Right now thou, there's no penalty for multiple tries, and there's also no penalty for laying more blocks than necessary. Adding those constraints could give a lot of replaybility to the game in future iterations :)
PS - I forgot to mention, but the tutorial is such a sweet addition!
