Heeey! This was almost what we originally went for with our sumo game. :D
It was a bit difficult to understand first, but with a little help from the comment-section I managed to beat the two easiest modes. But the two harder modes felt completely out of my reach. But I am a below average player in all games so that doesn't need to mean anything. :D
I enjoyed the solidity of it. Game loop is tight and well polished. The visuals are nice and feedback is great. It really feels like nothing was left out. A well take on the theme and controls felt satisfying as soon as I'd got the hang of them. :)
Nice work! :D
