An interesting idea, but this is barely a game. The only strategy to prolonging your existence on the game board is to move away from the dice, but even then, because the enemy die roll so quickly, it is still largely up to chance whether or not your position will be compromised by the dice roll. I could see this idea working if the timer was either slower or the game itself was turn-based as opposed to real-time. This would allow actual strategy in your dice's movement and allow you enough time to plan ahead based on the odds.
Unrelated to the game itself, but your game's zip folder contains your project's working files as well as the build. Not only that, but it also contains your Library folder, which takes up quite a lot of space. Perhaps consider just uploading a build of the game next time, because not only can people access your entire project now, but the download for this game was over 550MB (which is huge for a small game like this). It took quite a while for your game to download and that may turn people off and prevent them from experiencing your game. Other than that, I think your game could easily be taken further and expanded upon!
