Really interesting way to implement the jam's theme.
The mechanic that all objects stick to the player and the player becomes bigger, which makes the game more difficult, is very creative. However, you can get into a soft lock very quickly. I therefore reccomend that you have to be sure at all times, that the player does not get into a soft lock. For example implement a mechanic that the player can rotate, or you can rearrange objects that are stuck on the player.
Overall i think this game is great, with a really good concept. Nice work.
