Really cool vibes here. The humming of the engine is ominous. A lot of the things I would mention (the walking animation, the enemy death vfx, health bars) have already been mentioned and you were already aware. Though for my part I wasn't bothered by not having a compass, your signposting in-world is very clear.
Some way to respawn after dying without refreshing the page is a must though!
Really great work, especially for such a short time. Glad to see you're planning to continue!
