Fantastic presentation, and I'm impressed you managed to whip up RPG + turn-based-combat systems within the time limit! The variety in levels, abilities and all brought about by the dice rolls adds a lot of unique flavour too - a solid concept.
But I'm beefing with the spikes - the tight spaces in the overworld make navigation a little awkward in some spots already, but the spikes make it weirdly anxiety-inducing!
