Good Idea and really impressive for being new to unity in 48 h! Both drag and drop, fit to grid, random pieces and the snake AI - that's really not bad! It took me a while to realize I could only select pieces by clicking directly on the black part and not on the white part of the "button" they appear in. This was frustrating, because it felt glitchy that I often couldn't select and I started to wonder if there was a time limit/"cooldown period". I would also have liked a more clear way to outsmart the snake, since now it felt like the game could last almost forever and in the end it wouldn't be clear if I would be considered successful or not (or did I miss something?). Then again this is knitpicking for a game jam with a strict time limit!
