Wow, this was quite a game. I really liked the mechanic of being able to switch between liquid and solid in order to progress through the level. I also liked that the game had a tutorial that explained all the main mechanics, and also a few simple levels in order to let you learn some of the basic things before diving into more complicated levels. In addition, the game was very polished and had a good amount of levels considering that you only had 2 days to work on the game, and the art and audio were well made as well. One note is that the later levels are very tedious to complete, they require you to perform many difficult actions, that failing a single one of them will cause the level to reset. Having a few checkpoints on those levels so you wouldn't need to finish the parts you already completed many times before would make the game a lot less frustrating. Still, a very solid submission!
