Thanks for playing and the in-depth review!
There were several mechanics that are planned but couldn't get in on time (checkpoints and a health regen for example). As for the map I'm still working out what type of setting I'd like so I put something quickly together using unity assets and my own, that's probably why some things looked more detailed than others. The actual game will have a much more uniform style. I'll be honest I didn't spend as much time as I wanted on the enemies or general flow of the game. The boss, dialogue, cutscenes, and menu were implemented several hours before the deadline. My main goal with this prototype was to create a combat system, so it's very reassuring to hear you were impressed by it!
