This looks like a lot of work done in just two days! I personally don't like the minecraft aesthetic, but I do appreciate the amount of visual work put in. Having the character models, their idle animations, making the different kinds of blocks. And the amount of levels you made gave me a good 30 minutes of fun :). I'd say most jam games tend to get stale after 5-10 minutes and not all of them can be fun, but this one definitely surprised me with the amount of content and depth to the puzzles. I'd love to see more :)

The controls were a little finicky at times. When I'd click it wouldn't register on the blocks all the time. I found the difficulty well balanced at times where I'd have to play a few times to figure out the different areas and how to move around (I think Back in Black was the name of my favorite level for this reason). Contrast to that I felt like the labyrinth level was really easy (or maybe I found an unintentional win condition). There was so much to it I figured there'd be a lot to do but there ended up being a hole in the floor in the second room for the hero which let the anti hero jump up and win without much use of the colored blocks.
