I really appreciate you trying it out, and the super in-depth feedback (and bug report)! I'll definitely work on the clarity of the gameplay, and hopefully that will make the game more accessible and smooth to play. I've already got some ideas to subtly indicate what the outcome of a move will be, and how to warn players when shapes are close to starving.

Definitively a bug, once everything is done, the only things that should be able to share a tile are the Blue guys and the pond terrain (Right now he just eats the ponds)
Thanks again for playing, it means a lot to me
