Okay wow, really nice, polished descent-like! Immediately impressed that you got a full options menu in. The art style is very efficient and effective (I knew I had to play as soon as I saw the thumbnail). The world looks great and feels appropriately claustrophobic. Is the maze procedurally generated?
In terms of areas of improvement, I feel like the maze may be too complicated to grok (especially coming into the game). I see the alert about hostiles in the "green zone" but even with audio queues it's just an exercise of turning randomly until I see some green. Without landmarks I immediately decided that it was not going to be possible to learn the map. This meant that I didn't really get to experience that much combat (which I was aching for). When I encounter enemies I died a pretty easily (given how few opportunities I had to practise). I think simply increasing the density of enemies would improve this game, I'd like to spend more time dodging and less time searching.
Great jam entry. The team obviously knows what they're doing.
