Just played your game and it's indeed pretty funny! Especially since our games are very different despite having this similar core concept. I suppose we got inspiration from different games though (in my case: a boardgame called "Jungle Speed").
Glad to see you found it easy to understand! You're absolutely right about the yellow halo around the selected food. I actually noticed it towards the end of development and... kind of forgot to fix it as I was rushing through the last hours. An arrow would definitely have been a quick and efficient fix!
