I loved the game, very good for just 4 days. I loved the possibility of growing in some places and not having to jump haha. I really liked the collision boxes, it was very good. A little bit challenging at the end, but well, it worked out and I managed to win.  

Feel free to have also a look at my submission

Nice game considering the limited time you had, although the collision is pretty janky and it's easy to clip through the floor. Do you think you could try my game out?
