I enjoyed the classical music and the game ended up being quite a brain twister.
I appreciated the good level design on magenta level where it showed how blocks can be pushed before you needed to do that, but I was quite stuck on things going through holes for a while - some additional level design could have helped there. There is some really devious levels here, and I like it!
I think this game could be improved with a "take that turn back" button, like Baba is You - restarting a whole level can be rough!
I got the the last (navy blue) level but couldnt finish it after probably 10 attempts. I enjoyed playing your game though and it reminded me a lot of an old DOS game called "chips challenge". I also think you embraced the jam's theme well.
