Nice entry! I love the lighting effects, they really add a sense of atmosphere.
I think the overall gameplay is good - though it needs a LOT more feedback on things being hit. Flashes, knockback, damage indicators, anything to make it feel like I'm actually doing some damage!
The overall level was fine, it did the job. The bomb didn't carry over to the boss, which I thought was a little bit disappointing ;)
Otherwise it was a solid entry - good job!
