Wow. That was really fun to play. We actually had to force ourselves to stop playing to do the review or we'd have no time to play other games! The dice combat was really innovative and worked extremely well. You really had to think about your next move and whether to block or attack or lock a dice. Then you added the extra abilities and it had a whole new dimension. Brilliant.
It wasn't just one level either, it kept going with levers and more enemy types. The sword and shield graphics were great and overall the graphics gelled nicely. Movement was smooth and also responsive. The lighting was good, especially switching into the shadow world (your duality theme we assume).
The game probably plays really well on a touch screen, like an iPad, which is a nice feature. However, the alignment (also possibly sizing) of those movement buttons on the UI is randomly a few pixels off here and there. It's really trivial but it bugged the hell out of us.
It also wasn't obvious that you had to place the 1 die onto the altar directly since there wasn't a box for you to drag it to like the combat abilities. We nearly stopped playtesting when we couldn't work that out at first and it would have been travesty had we done our review only on the game to that point.
Well done with your game. This has got to be high up there in the jam ratings and it's well deserved. A simple but also deep and strategic mechanic that's a winner for us. We'll be playing this one again!
