Thanks for the feedback! We're not currently planning on continuing working on it, it's hard to think of a place we could introduce more content without harming the minimalist design, but interface and quality of life improvements are definitely something that we might come back and add in.
The menu hiding enemies is something that we have been receiving a lot of feedback for, so if we release a post-jam patch or whatever, that's definitely something we'll address.
And your offer to supply death screams is greatly appreciated, we'll make sure to call on you if we need more :)
