Very funny game, especially the masterpiece OST and beatbox sound effects :D
Obviously, some graphics adjustments would make the game even better, but not too many as the game would lose its funny feel and appeal. Plus, add some more levels! The puzzles were nice.
I noticed that clicking on multiple shapes without placing them places them all in the same place, maybe try making shapes selection reset the previously selected shape from the menu if it was not places.
Although the "music" was amazing, it can become repetitive and , I'd suggest to add player options to adjust it or mute it in the main menu (though muting it would be a capital sin), and maybe to also add more music tracks, different from level to level, maybe referencing the different shapes the level introduces.
Very funny puzzle game overall, with simple mechanics but a clever core concept, and obviously very on point theme interpretation!
