A solid entry with all the basics of a crawler; movement, XP, monsters, combat log, music and sound, even a brief intro. No bugs that I found, which puts it ahead of my entry.
Some different monsters and some more loot or pickups other than medkits would have been nice. The game did feel a little light on the "cosmic horror" theme, given that it was just some empty halls with some easily-defeated enemies; without any other storytelling it felt more like just a monster hunt.
But overall this seems like a good framework to build on. Thanks for submitting it!
