The text was a bit hard to read. You might want to pick a slightly clearer font.
The pixelated rendering style was interesting. We're guessing it was actually fully 3D and this was a post-processing effect? Our preference would be to not render it pixelated. Although classic dungeon crawlers had limited palettes, due to the hardware, modern ones like Grimrock and Vaporum are much easier on the eye and make use of modern graphics capabilities and we feel they're better for it. This is of course very subjective and just our opinion.
Very interesting idea, although a bit gruesome, to find sacrifices to boost your character stats.
It was nice to change music between environments. It may have been a bit too upbeat for the task at hand though.
It would have been nice to see how long was left on an attack cooldown.
We found ourselves getting lost in the woods very easily. Perhaps that was the idea! A map would be really useful.
We found a graveyard with lots of swords that we couldn't pick up. Were we missing a key to press?
Slow health regeneration was nice to have.
We really enjoyed the game and we think is has potential going forward.
Well done on your amazing first game jam entry. You're sure to have success after you graduate. Best of luck in the games industry.
