Good looking, but hard. Movement should be fluid, more like Supaplex than Boulder Dash, now it is bit disorienting (even though you can't rotate camera). Few times hud-dice and player-dice went out of sync I think, making finishing level complete guesswork. Underlying mechanic is solid design and power ups/abilities work well. It would be good idea to make abilities show on side that it is attached on for post jam update. So if side 6 has 3+ attached, there would be sticker over 6 that says 9. And for weapons too similar thing. This would drop need for UI-dice altogether.
All in all, good idea, good graphics, has potential for being nice little game.
