Whoa, a very ambitious project for this jam. It's great to a 3rd person game mixing ideas from a Metroidvania. I liked the atmosphere and the game assets worked well together.
Some thoughts:
- There's some audio clipping from all the loud explosions (seems to happen most in the first area). I'd recommend turning them down to help prevent that.
- The camera moved too quickly for me. I think it's a mouse sensitivity issue (I have the same issue with my game, forgetting to add a mouse sensitivity slider).
- I think it'd be good to add some sort of indication that you can interact with certain objects. Maybe a brighter outline, or a 'Press E' sort of thing.
Overall, I'd be interesting to see where this could go!
