really well made puzzle game with a lot of potential, i spent a lot more time than i thought i would solving these. i did feel like the rotate was a little odd to use with the 3 buttons. i think maybe having it so that you click and hold to place a block and then drag it in the direction you want it to point similar to the conveyer belt and for the wide blocks have the drag be where the other part of the block would be.
all what is missing is some sound effects and a lofi-like theme, good stuff!
