Definitely an interesting setup that I would be very ,keen to see more of.  Though there's not too much there right now which to be fair, we're talking 48 hours so it's pretty good for that.  The movements a little iffy in my opinion, but it's decent, I just tended to fall off quite a few ledges throughout the map without many options to get back up from there.  

Though I will say there's not too much feedback throughout, there's some visual feedback on getting a new weapon from the dice grenade, but not really any on the damage to enemies.  Or audio feedback on taking damage/dealing damage as well.  Which was a little weird to see, but makes a bit of sense.

One other thing as well is I feel like with how central the dice are, having them be so limited is a little weird.  Cause it makes it so most of the game you're playing with one weapon, rather than being forced to switch up your gameplay.  I thought it would've ended up being some sort of, I guess probably wave shooter where the enemies spawned and you could use the dice grenade either when you wanted and have to avoid it, or when you ran out of ammo to work as your reload but with the drawback that the weapon might suck.

Although there's probably some more interesting twists that could be done with that, that's just where my mind went to, it's hard to know what would work.

Overall though an interesting interesting setup with some decent twists that would be cool to see expanded in possibly the same format, with some tweaks, or maybe a different format for the levels.  We'll see.
