Mario Game: Super Mario Block Puzzle Game

This is one of my favourite games I`ve made, level-design wise. Best I`ve done IMO.Anyways for some reason Mario has to go through a series of levels involving puzzles that involve picking up and dropping blocks.It features 20 levels, 2 worlds, and 2 boss fights, as well as a preview of what the third world would have looked like if I could be bothered with finishing this.Shift jumps, control picks up blocks. I know there are a few glitches, especially one where you sometimes get stuck in blocks but whatever. I`m too lazy to fix them.
