Very cool game. Love how we both did something kinda similar yet totally different at the same time with the dual snake thing (tho mine is 1 snake 2 headed). The hunger system was something I wanted to add to my game too but didn't really have the time, the version I ended up submitting was made within like a 3rd of the total jam time, aside from most of the art that I had made for a version of the game I started first in another game engine.
If I had one peeve with the game it's that the input actions seem to buffer one move later than they should so when you are going left for example then press up before next move happens, you'd logically go up next move, but instead you go left then up. Seems to make precise movement kinda tricky, which especially with the higher speed modes is kinda tough, but honestly even more noticeable on the slower ones.
Nice little project tho and well done! 💛
