This is really great considering you did it alone!
I loved the colour palette and the graphics, I was a bit confused at the start because I didn't read to turn on the lights with the switch (if it was written anywhere 🤣), on the third mission I had the same problem because I didn't read the mission (I was dragging the wrong crates), I think that you could have left the mission visible all the time!
Another thing I didn't understand is the rope, can you grab it or is it just a collider? I tried to pick it up smashing all keys on the keyboard (and I killed me several times with R)
