Nice concept! I would have liked to seen it taken a little further - maybe the dice could be rolled again by something in the middle of a round?
There were also too many subtle speed changes caused by the dice - would have liked something a bit more varied and interesting. For example, what if, instead of just a simple speed increase, the enemies could get some kind of dash attack? The enemies were a bit easy - another enemy type, perhaps one that could shoot projectiles, could make things more interesting!
i enjoyed using the rocket launcher, it was pretty satisfying. The game is pretty fun and has a lot of potential!
