Hey! What you did is super impressive :)! I'm a huge fan of jam games with an online element (focusing on it myself) and a real-time multiplayer game is cool to see!
I think the idea of fighting others with dice which deploying different strategies is really cool, not sure I like the implementation here though. The positive feedback loop is very real and there's no way to "farm" on your own like in Agar.io (for example). So my tactic was just to run into players with less dice and repeat. Maybe if there was more "dicebuilding" and ways to evade battles with others, the game would be more strategic.
I understand you didn't have time for much else though. Well done on the networking!
