Lovely puzzle ideas and tool we got, the last room was especially tricky to figure out! There only a few small things I could bring as negatives, because overall the game was well thought out and executed. Those two are the offscreen teleport and the fact that rotation while not moving was explained later than the first pebble level where we learn the basics.
Graphically the game looks lovely, there is a certain charm to the palette choice and the sprites look neat, always love me some sketch like art!
Sound and music the game also excels, awesome work with it!
Overall a lovely experience and brain twister you got here!
